High-order resonance of three axis suspension wire actuator in optical pickup;

Influence of processing factors on the dynamic characteristics of optical pickup actuators;

Improvement of high frequency dynamic performance of actuator in optical pickup by finite element and sensitivity methods;

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.

And the experiment simulation for some actuator shows that the method is very convenient and effective to most kinds of optical pick-up.

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

In this paper a new type optical probe is designed.

The development of a new DVD optical pickup parameter adjust equipment;

Parameter adjust system of DVD optical pickup based on labVIEW;

The research of evaluation methods and test equipment of DVD optical pickup isnot only the key to research, develop and produce DVD optical pickup, but also themain factor to restrict the development and improvement of Chinese pickup industries.

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.
