Laser profilers are laser displacement sensors that collect height data across a laser line rather than a single point. This enables 2D/3D measurements such as height difference, width, or angle to be performed using a single sensor. In addition to height data, KEYENCE profile sensors also collect intensity data to provide a stable solution for inline measurement and inspection. The lineup includes a wide range of sensors to support a variety of applications and industries.
Perform 2D/3D measurement and inspection in line with the LJ-X8000 Series. Our most versatile lineup of laser profilers offers 3200 points/profile, making it easy to accurately measure any target shape or material from high-resolution images. The laser profile scanners are compatible with four different controller options, allowing users to select a setup that perfectly aligns system capability with any application requirements. The maximum laser linewidth reaches over 720mm (28"), and multiple can be paired together to scan even larger targets. Programming for these high-performance sensors is completed in three simple steps, making accurate in line 3D measurement accessible for users of any experience level.
Improve Reliability with 4x More Resolution
Capturing the true shape of a target is critical for performing reliable inspections. With 3200 points/profile, the LJ-X8000 Series captures target shape in high resolution, enabling accurate inline measurement.
- Surface dependent
- Stable on any surface
Maximising resolution and target detection
To improve the resolution of the sensor, the number of pixels on the CMOS needs to be increased. This can be accomplished by making each pixel smaller; however, smaller pixels can result in insufficient light detection, causing an inaccurate profile on some targets. For the LJ-X8000 Series, we’ve implemented new technology to create a laser profiler capable of high-resolution measurement on any target.
Parallel light is emitted using a cylindrical lens designed to prevent the reflected light from scattering across the surface of the target. This ensures reliable reflections from any shape or surface.
Large-aperture receiver lens
The sensor is equipped with a receiver lens that has 3x more area than conventional models, increasing the received light intensity. This allows the sensor to produce stable profiles in any environment.
This newly developed CMOS enables high-resolution measurement using 3200 points/profile, while delivering improved imaging capability on targets with varying reflectivity.
Profile Alignment Function
When creating a 3D image, the positions of each 2D profile are adjusted in the X, Z, and θ directions. This eliminates the impact of vibration and eccentricity as well as bends and curvature in the target, creating an optimal image for inspection.
Without profile alignment
Without profile alignment, the target image is distorted by vibration, making it impossible to perform accurate inspection.
With profile alignment
Profile alignment allows for an optimal 3D image to be created. This achieves stable, inline inspections for dents, chips, and other defects.
