Abstract

The term "pixel profile" refers to the spatial distribution of electric field amplitude within the aperture of a single pixel of a spatial light modulator. We discuss the use of non-uniform pixel profiles for increasing the energy throughput of spatially discrete coherent optical imaging systems. Prolate spheroidal pixel profiles are shown to be optimal and can produce throughput gains of up to 32% for optical systems with rectangular symmetry and 27% for those with circular symmetry. These throughput gains are shown to impact the capacity of volume holographic data storage systems. A simple M/#-based analysis predicts a 15% capacity increase as compared with the use of uniform pixel profiles.
