The experimental result shows that the depth of hardened zone and smoothness of surface can be controlled conveniently by varying the power output beam diameter and scanning rate of laser light.
试验表明:通过调节激光器的输出功率、光斑直径和扫描速度可以方便地控制熔化层深度和表面平整度。

Focusing on the problem such as slow scanning speed, complex system design and low light efficiency, a simple method to obtaining optical sectioning in multiple-beam confocal measurement was proposed.
Electonic plate scanning: a process that USES a lightbeam to scan the offset plate for the purpose of recording the position of image areas on the plate and to evaluate the amount of ink required.
