A kind of long rail measurement,based on wedge-shaped plate interference,has been developed,which is one of the important branch of geometry measurement.

On the basis of analysis of and research on the current laser spectrum detection technology, the paper proposed the protocol that, use fiber optical antenna and modified wedge interferometer to obtain the laser interference fringe, t.

For accurate measurement of far-field divergence angle of Gaussian beam,a method is presented based on wedge plate shearing interference.

Design of white-light interference micro/nano scanning system controlled by SPCE061A

The theoretical analysis indicates that,with white-light Michleson demodulation interferometer,the distance between two neighboring white-light interference peak is equal to half of the light length difference between the two arms of the Mach-Zehnder interferometer.

Based on the white-light interference,a vertical scanning white-light interfering profilometer was designed.

A kind of gas detector with light interference based on single-chip microcomputer was designed, which took AT89C2051 as center of control and processing.
