YTR-6303 # Galvanometer-based Laser Scanning Experiment

SUMMARY

The laser scanning oscillator consists of an X-Y optical scanning head, an electronic drive amplifier and an optical reflector lens. The signal provided by the computer controller drives the optical scanning head through the drive amplifier circuit to control the deflection of the laser beam in the X-Y plane.

The YTR-6303 laser scanning experiment system is mainly composed of computer, laser, scanning mirror driving power supply, laser power supply, optical path system, etc. Its working principle is that the laser emitted from the laser passes through the optical path system, and then is projected to the XY plane of the observation screen after being reflected twice by the X-axis and Y-axis mirrors in the mirror scanner, forming a scanning point. Any complex plane trajectory can be achieved by controlling the deflection of the two lenses of the oscillator.

Experimental purpose

1、To understand the construction of the laser scanning optical path.

2、Determination of XY scanning center deviation

3、Measurement of F-theta lens focal length

4、Linear relationship between different focal lengths of F-theta lens and marking pattern

5、Pillow distortion and barrel distortion

6、Demonstration of laser imaging by laser scanning oscillator system

FEATURES
