Combined optical testing system with projection and schlieren

摘要

PROBLEM TO BE SOLVED: To relate a composite optical test system of projection and schlieren, and to the technical field of optical test of projection and schlieren. According to the present invention, a projection telephoto system and a schlieren photographing optical system are separately formed by applying a combination of optical characteristics for moving two lenses in a set of test systems, and a set of optics. Achieve that the system device has two functions, a projection optical system and a schlieren optical system. According to the present invention, a device having two optical test functions based on two different optical principles can be achieved by one device, the design and manufacturing cost of the test device can be significantly reduced, the function of the test device can be increased, and the test work can be performed. Conveniently develop and save space for test equipment placement. [Selection diagram] Fig. 3
