Lcd Tv For Calculate Holographic Aspheric Testing Technology Research,

In this thesis, a technique of testing aspherics is discussed. We first describe the method of testing aspherics using computer-generated-holograms. Because traditional method of making CGH is time-consumed , high-cost and easily introduces error during making CGH, a new method of real-time testing aspherics is developed on the basis of the discussion of the optical character and the appl i cat ion in other optical field of LCTV. First we analyze the feasibi I ity of the new method in theory, then a we 11-connected experiment is done and the new method is proved to be feasible. In the last part, an aspheric is tested and it is analyzed that testing the aspheric with high precision is absolutely possible.
