- The most common way to acquire 3D information from a real scene is to use multiple cameras. If this approach is suitable for visible light, it is more difficult to realize in unconventional spectral ranges such as ultraviolet or infrared because the cost of cameras is much higher than for the visible domain. Holography is a technique that enables to acquire 3D information by recording interference patterns. Conventional holography is very sensitive to vibration and outside light, but optical scanning holography (OSH) is a technique based on heterodyne detection that enables to ease greatly these constraints. In addition, since OSH is based on single pixel detection, there is no need to use high resolution camera. In this study, we describe the implementation of an OSH set-up for acquisition of holographic information with a single pixel sensor.
