Magnification Digital Test Technology Based on Image Processing Technology

Magnification is an important performance parameter of telescopic optical system, based on the traditional test theory and method, combined with CCD technology, photoelectric automatic focusing technology, precision machinery technology, modern electronic technology, automatic control technology and computer image processing technology, put forward the corresponding digital test method, in order to improve the objectivity, accuracy of measurement. Standard parts was tested on the measurement system, experiments proved that the magnification testing accuracy <;1%.
