conference on current developments in lens design and optical engineering III
作者: Wei, N Gong, MI Yan, P Zhang, HT Tsing Hua Univ Dept Precis Instrument Digital Photon Lab Beijing 100084 Peoples R China
We have developed a new method other than traditional technique based on ray tracing and optimization algorithm to design arbitrary aspherics. Analytic definition of the aspheric surfaces is done away with and numeric... 详细信息
