Paper Abstract

Coded aperture imaging technology have been utilized [1] for imaging in various space missions primary associated with X-Ray and Gamma ray sources. The need to extend the coded aperture technique into Visible/IR is pushing the technology and so geometrical features become smaller [2,3]. As the geometrical feature become smaller, second order effect such as diffraction become noticeable. The effects are typically isolated in order to improve Signal-to- Noise Ratio (SNR). In this paper we are exploiting diffraction and interference to use as a coding approach. We propose a coded aperture transmitter/receiver system capable of hiding information (bits) inside the diffraction nulls.
