Use laser as the light source, use quadrant silicon photod as the detector, and recur to the principle of triangulation, the laser light reflected from the vibration source surface will generate displacement signal on the photoelectricity detector, and then magnification the displacement signal, acquisition the magnitude of voltage by A/D module, and display the result on the computer.

Four quadrant photo-diode detector are used as electro-optical 2D position sensitive elements.

When the intracavity He-Ne laser is used as illuminant,the reading of photoelectricity galvanometer is instability on the experiment of silicon photo-cell.

Experimental equiment of silicon photocell based on single bus technology;

Study on Test Method for Relative Spectral Response Characteristic of Phototube and Silicon Photocell;

Measuring the band gap of silicon using silicon photocells;

The method, using silicon photoelectric cells to test uneven influx distribution, has been proved to be effective experimentally.

This instrument uses LCLV and silicon photoelectric cells subtly,which can survey,adjust and control automatically,and improve the work efficiency of shooting fine hologram obviously.

We report a micro-laser power meter,which is made of silicon photoelectric cell for measuring the laser power from micro-focus systems.
