Paper Abstract

We examine a multi-aperture imaging system using a Boulder Nonlinear Systems (BNS) Spatial Light Modulator (SLM) for a wavefront control device. Such setup allows for focusing and tracking of a target over a fine angle while preserving high resolution imaging in a compact system. The SLM provides the necessary phase to focus, track and image a target. The effects of implementing a SLM on the multi aperture imaging system were investigated. The stepped phase and use of 2π resets from SLM was modeled for simulation. The result confirms the expectation that a periodic reset of the quadratic phase bowl introduces phase grating modulations, which produces "ghost images" around the desired zero order image.
