Investigation of beam splitter reflection/transmission ratio on single beam multiple intensity reconstruction towards a single shot setup

Abstract

A simulation model that enables optimization of a single shot multiple plane recording technique utilizing a series of beamsplitters is proposed. Conventional single beam multiple intensity reconstruction is restricted to static or very slowly varying objects due to the mechanical movement of the single CCD used. In order to obtain the phase of dynamic objects, modifications must be done to enable simultaneous recording of the multiple planes. One technique is to use a series of beamsplitters to divide and redirect the diffracted field, and then utilize a number of CCD sensors to capture the redirected light fields. Physical implementation of this technique requires choosing the optimal number of beamsplitters and their respective reflection/transmission ratios.
