ALT Co., Ltd. showcased their laser scan projector, the ALT-6600-520, at the recent OPIE ’23 exhibition. The projector uses laser diodes to emit a laser line for three-dimensional measurements. One method involves generating a fixed pattern, while the other scans a laser line and generates a pattern. Liquid crystals and scanners like DMDs are often used to produce patterns, but the ALT-6600-520 uses Hikari MEMS. The laser diode produces a line that is almost in focus regardless of distance, making it an advantage for measuring workpieces with large unevenness. This technology has been used for 3D measurement, and with different thickness of stripes, they can be matched to the frame rate of the camera for better results. Overall, the ALT-6600-520 offers a more advanced solution for those seeking accurate laser scan projections.Generated by OpenAI
