Featurestool adopts multi-band laser +I-SDP.When using traditional laser, the transmitted light spots will cause mottled patterns. This is a laser interference problem caused by a single wavelength laser. The sensor of this measuring tool solves this problem by using multi-band laser. Because the shadow is formed more clearly on the CCD, the sensor maintains a high degree of stability, even for objects that are traditionally difficult to detect (such as transparent objects). Because I-SDP (Parallel Computing Chip) is integrated in the receiving target, the sensor can perform data processing at high speed and minimize interference.Receiving target position display is extremely easy to use.The position display on the receiving target allows the user to see how the target is detected. Users only need to observe the red light indicating the light receiving position and the green light indicating the detection position to prevent installation or setting errors.easier optical axis calibrationThe position display makes it easier to calibrate the optical axis. Just adjust the receiving target to make all the lights on the position display turn red, and the optical axis can be easily calibrated.5.
