The invention provides an optical
athermalization design detection
system and detection method. The
system comprises a communication module, a video acquisition module, an image definition evaluation module and a temperature compensation and focusing
curve fitting module; the image definition evaluation module extracts the feature vectors of a
video image in real time, analyzes the feature vectors according to an
image quality discrimination
algorithm, and obtains an optimal focusing quantity under a current temperature point when the image is has the highest definition through traversing a focusing range; and the temperature compensation and focusing
curve fitting module fits an optimal focusing quantity curve in an entire airborne ambient temperature range according to optimal focusing quantities under different inputted temperature points. According to the optical
athermalization design detection
system and detection method of the invention, airborne ambient temperature is simulated, so that testing is performed; the optimal focusing quantity curve under different temperature is drawn, and is solidified into a photoelectric product, so that the
athermalization design of an optical system can be realized. According to the detection system,
image quality detection is objectively evaluated through adopting image definition, and a temperature compensation and focusing curve is automatically drawn, and therefore, labor and time can be saved. With the detection system and detection method adopted, multi-batch photoelectric products can be tested, so that
repeatability is high.
