laser-driven flyer device is one of the important ground systems to simulate hypervelocity impact of space debris to spacecraft.

This article introduces the feasibility test of laser-driven debris.

One-dimensional shock loading on the material can be realized using the technique of laser-driven macro-flyer plate and is of applications to the research of high pressure equation of state(EOS) and dynamics under high strain rate.

Injection moulding of OPU in laser head;

A new design of LD sidepumped laser head and compared the InputOutput character with the old pump structure by using Nd∶YAG as laser material are Introduced,a new crystal named Nd∶GdVO4 in the new laser head structure is experiment and the output of 42.

Improvement on measurement precision of laser probe using image optimization method;

In order to realize non-contact auto-measurement of revolving parts,an offset auto-adjustment device was de- signed by using a laser probe as the feedback control element.

A stereovision inspection system for measuring free-form surface is introduced which consists of coordinate measuring machines (CMM) and a laser probe.
