ALT Co. Ltd. showcased its laser scan projector, ALT-6600-520, at OPIE ’23 trade show. The projector uses a laser diode to generate a fixed pattern or emit a laser beam on a line and scan it to generate a pattern. Liquid crystals are used to produce these patterns and the laser is almost in focus whether it is near or far, making it ideal for measuring workpieces with large unevenness. This projector has been used for 3D measurement in the past.Generated by OpenAI
