Digital holography benefits from interferometric amplification, which enhances sensitivity. Coherence-gated digital holography allows for the suppression of noise sources such as multiple scattered photons and other light sources. In addition, digital holography provides access to optical phase information, which is an important metrological parameter for three-dimensional measurements. The aim of this study is to investigate the potential of digital holography as a new sensor concept for the environmental perception of autonomous vehicles under difficult visibility conditions. Our experiments are conducted using a 27-meter-long fog tube and serve in particular to characterize the capacity to effectively filter multiple scattered photons based on their coherence property. From the comparison between holography and time-of-flight (ToF) imaging, it follows that although the ballistic photon filtering works significantly better in ToF, the increase in sensitivity due to the interferometric amplification effect results in holography outperforming ToF. In addition, we combine these results with previous experiments and show the importance of the advantages of digital holography for environmental perception through scattering media.
