Single camera vision coordinates measurement based on feature points imaging of optical probe has the characteristics such as large measurement space,high measurement precision,measurement on-line and so on,so it is one of good foreground technology schemes that may replace traditional large-scale coordinates measurement machine.

A posture error compensation method of optical probe was presented in this study.

Palm and finger are usually preferred to be used as measured sites in optical probe-based measurement because they both are convenient and easy to be measured at any time.

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.

A precise and fast 3D coordinate measuring machine, which is composed of a laser probe head and servomechanism with high performance, was developed utilizing precise control, positioning optimization, approximation of deceleration with three levels broken line, online position correction and smoothing algorithm.

Design and calibration on optical probe used in chippedestal welding machine;

In this paper a new type optical probe is designed.

The grating fringes of on the subimages are generated with a interference imaging optical head.

Optical head is the heart device of Optical disc storage system, and a separate optical headseparates focusing objective from other parts of optical head with the aim of reduced the weight and volume of the mobile parts of optical head and increasing its flight speed and realizing highspeed access.
