Abstract

The utility of optical phase conjugation to correct for distortions acquired during transmission through a random media is well known.^1–4 However, as information propagates through an optical system, it may undergo irreversible losses due to finite system apertures. For example, in Fig. 1 at plane P1 (input object plane) an aperture would limit the number of pixels transmitted, at plane P2 (Fourier plane) an aperture would limit the number of Fourier modes transmitted, and at plane P3 (phase conjugate mirror (PCM) plane) an aperture would limit the number of scrambled modes transmitted. Losses due to these apertures contribute in a complicated fashion to decrease the overall image fidelity at the output plane P4. However, it has been shown⁴ that reciprocity can be utilized to simplify the analysis of such complicated systems.
