Phase-Coded Volume Holographic Gratings for Spatial-Spectral Imaging Filters

Abstract

We present a design of phase contrast filters embedded in a three-dimensional (3D) pupil to form phase-coded volume holographic gratings (VHG) for spatial-spectral imaging. The phase-coded VHG improves image contrast and results in strong filtering properties to acquire weak phase structures of an object. In addition, incorporated with in-plane angle multiplexing, the multiplexed phase-coded VHGs enable obtaining weak phase information from multiple depths of an object. We experimentally demonstrate the multiplexed phase-coded VHGs for spatial-spectral imaging to enhance unstained features of spatial-spectral images of human breast cancer cells. © 2012 Optical Society of America OCIS Codes: 090.7330, 090.2890, 090.5694, 110.0180, 110.4234
