Reflective Distance Sensors

Laser Displacement Sensors | KEYENCE America (24)

IXSeries image-based laser sensors can measure height anywhere within the area. Camera-based image recognition allows the laser to detect the height of the target point even when workpieces are not perfectly aligned on the production line. The height of where the laser hits the target will vary if the target is tilted or if the target itself is different, but the IXSeries can identify the difference in height against the reference. For example, in a parts assembly line, a single IXSeries unit can not only check for the presence of parts, but also perform seating checks and other height-based inspections. Thanks to its ability to detect height differences, the IXSeries is also free from false detections and errors in the presence of glare from glossy surfaces of metal parts or when the detection target point has the same color as the background, offering stable automatic inline differentiation.

KEYENCE's 1D laser displacement sensors enable non-contact measurement of a target's height, position, or distance. By pairing multiple sensors, measurements such as thickness and width can also be performed. High-accuracy displacement sensors can be grouped into two categories: confocal and laser triangulation. Both provide accurate, reliable solutions for non-contact measurement, but depending on the application, one type may offer an advantage over the other.

(Video) Confocal Displacement Sensor - CL-3000 Series

Descriptions of the various types, measurement principles, and advantages of 1D laser displacement sensors can be found below.

Multi-color confocal method

Confocal displacement sensors emit and receive light on the same axis. Multi-color confocal sensors use a light source that emits multiple colors (wavelengths) of light that each have a unique focal distance. The sensor measures the distance to the surface by detecting which color is currently focused on a target. Keyence's CL-3000 Series sensors utilize a brighter light source than conventional models, producing stable measurement results throughout the full range, regardless of the surface's reflectivity.

Laser triangulation method

Laser triangulation based displacement sensors utilize the return angle of light reflected from the target to calculate position. Laser light is emitted from the sensor and is reflected off the target surface. Some of that reflected light is focused by a lens onto the receiving element in the sensor head. Depending on the target's distance from the sensor, the return angle of the light will change, striking a different position on the receiver, which can be detected. The LK-G5000 Series employs a high resolution CMOS to stably measure small changes is displacement.

Confocal surface scanning method

Surface scanning confocal laser displacement meters utilize a tuning fork to rapidly vibrate an objective lens. This moves the focal point of the laser up and down through the measurement range at high speed. The reflected light is focused on a pinhole, where some of the light passes through to the light receiving element. When the light is focused on the target, more intense light passes through the pinhole and the objective lens' position is recorded and correlated back to target position. KEYENCE's LT-9000 Series uses a tuning fork to scan in the z-axis and an oscillating unit to scan in the x-axis, producing high accuracy and stability while employing an ultra-fine beam spot of ø2µm.

Benefits of Laser Displacement Sensors

One of the major reasons that these sensors can measure targets with diverse materials and characteristics is because they can perform highly precise non-contact measurements. The optimal laser displacement sensor can be selected to match the application or target material (such as transparent or glossy targets).

If the target is made of metal or some other hard material that does not scratch easily, it can be measured with a caliper, micrometer, or other such instrument that touches the target directly or with an LVDT or other such contact displacement sensor in an inline situation. However, errors may occur due to the measurement pressure when the target is soft. For delicate targets whose quality is affected by contact such as wafers, thin films, and sensitive hairline metal surfaces, non-contact laser displacement sensors can be used to measure without worrying about errors and target damage. Because they allow for stable, non-contact measurement even of transparent or glossy surfaces, laser displacement sensors enable a wide range of possible applications.

Accurate device positioning is necessary in the automation of processes such as coating, welding, and component mounting. The compact, lightweight head of KEYENCE’s multi-color confocal method laser displacement sensor can be easily installed on devices and accurately determines the distance to the target, allowing for highly precise position control without sacrificing device operation.

Separating the spectroscope unit and leaving the lens as the only key part in the head has given the CL-3000 confocal displacement sensor a compact and lightweight head that can be installed easily on devices. Measurement is performed with light along the same axis, so the heights of narrow gaps in targets can also be measured with no blind spots. Furthermore, the head generates no errors due to heat or electrical/magnetic noise, ensuring stable measurement. For device control, laser displacement sensors can measure target height at high speeds, feeding back this information to control devices. This allows for heights of stepped targets or targets that are slightly tilted during conveyance to be measured in real time. The result is that quality can be maintained in automatic processes.

Laser Displacement Sensor Case Studies

Thickness measurement of glass (patterned on one side)

When the surface reflectance differs between the glass surface and the pattern surface, tracking errors traditionally occur at the pattern surface when thickness is measured with laser displacement sensors positioned on each side of the glass. The CL-3000 confocal displacement sensor uses a multi-color confocal method that measures the position where the projected light is in focus, allowing for stable and highly precise measurement unaffected by differences in the intensity of the light reflected from the target. This minimizes the effect of tracking errors, improving the inspection cycle time.

Dispenser nozzle height measurement and control

Ensuring advanced, high-accuracy, automatic coating requires not only a sophisticated dispenser robot but also a high-performance displacement sensor that moves together with the nozzle, working as the eye of the dispenser. Installing the CL-3000Series confocal displacement sensor so that it follows the dispenser nozzle enables nozzle height control through real-time measurement and feedback of the target height. The compact and lightweight head can be installed easily next to the dispenser nozzle and reduces residual vibration when operation stops. The multi-color confocal technology uses a coaxial system to provide a wider measurement range and ensures stable height measurement and feedback control without being affected by the transparent, mirror, or glossy surfaces of materials or by shapes such as concaves, differences in height, and inclined or rounded surfaces.

Frequently Asked Questions About Laser Displacement Sensors

CL-3000Series confocal displacement sensors can stably measure not only transparent glass but also a wide variety of target materials and shapes with high precision. Of course, the non-contact measurement eliminates the concern of damaging the glass. With the CL-3000Series, up to six heads can be connected simultaneously to a single controller. For example, the glass flatness can be checked stably by measuring the four sides and the center of the glass with a system consisting of one controller and five heads or by measuring six ends with four to six heads.

Generally, diffuse reflections occur due to the laser light penetrating into the inside of the PCB when it is measured with a laser displacement sensor. This may lead to unstable measured values. KEYENCE CL-3000Series confocal displacement sensors can emit laser light at multiple wavelengths to calculate and measure just the wavelength band of the light that brought the surface of the target into focus. Stable measured values can be obtained with high precision even for PCBs and other such targets easily penetrated by light.
