Abstract:
Digital holography DH has been demonstrated to be an effective tool for tactical applications which involve in low signal-to-noise ratios SNR. In practice, DH uses a strong reference beam from a local oscillator LO to scale SNR, however since DH relies on the interference of a signal beam with a mutually coherent LO, the coherence properties of the master oscillator MO can degrade system SNR for long range engagements. In this thesis, a digital holography system in the off-axis image plane recording geometry was assembled and used to measure the effects of the coherence properties of the MO on SNR.
