Efficiency Quantification for Pulsed-Source Digital Holography
Abstract
The efficiencies of a digital holography (DH) system in the pulsed configuration and the off-axis image plane recording geometry areanalyzed. The system efficiencies of an infrared-wavelength DH system in a homodyne-pulsed configuration are compared to those of a visible-wavelength DH system in a homodyne-continuous-wave (CW) configuration. All measured efficiencies were found to be consistent between systems. The consistency of efficiencies also showed infrared DH systems are viable but degraded due to infrared detector technology. A new efficiency, called the ambiguity efficiency, was experimentally verified. Also, a DH system in a heterodyne-pulsed configuration was characterized and compared to a homodyne-pulsed configuration. System performance was consistent. The effect of spectrally broadening the source laser of a DH system in the heterodyne-pulsed configuration was analyzed.
