摘要
本文把狭缝式鼓轮高速相机成像看成两个线性系统串联而成 :一个是摄影物镜到狭缝 ;另一个是狭缝后的目标物到感光胶片。动态拍摄时的 MTF用相乘律法则进行计算。讨论狭缝相机的物镜 MTF测试进行讨论。对动态拍摄时的不同Δv值提出了修正数据。
MTF test of the field lens of narrow slot cameras is discused.We regard the formation of image with the high speed camera of tub wheel as two series faces of linear system,one is the face that is from the field lens to narrow slot,the other is face that is from the object to the sensitive film.The MTF of photochronograph is calculated with the multiply principle.We provide the correctional data for different values( Δv ) according to photochronograph.
