Making research on space intersection angle measurement system for three-line mapping camera in thermal-optical test. Designing the test system and making research on the test method for intersection angle. The method for quantitative measurement is put forward. The requirement of thermovacuum test equipment and optical measurement field is interpreted in detail
especially the collimator and special reticle. At the same time
the needed preparation is issued before thermal-optical test. The measurement software system is made with Labview software. The three–line mapping camera intersection angle is tested with quantitative measurement. The results show that the change of intersection angle is below when the temperature operating condition is changed. In a word
quantitative measurement method can get the accurate change of intersection angle. The measurement data can benefit to the analysis on earth.
