Paper Abstract

A set of special driving circuits for CCDs to absorb the image pulse produced by laser pulse was successfully made. An optical system of short light distance with 30 power was set up to improve the resolution of the measurement of the displacement. So, the automatic measurement of thermal expansion is realized on the laser pulse thermophysical properties equipment, which is a main apparatus in the thermal physical properties research field.
