Abstract
Methods and devices for holographic imaging are disclosed. In some embodiments, a holographic imaging device is disclosed that includes at least one radiation source, a reflective surface, and an image sensor. The at least one radiation source may be configured to emit a radiation wave towards the reflective surface and an object positioned on or near the reflective surface, where the radiation wave is reflected by the reflective surface to produce a reference wave and is reflected directly toward the image sensor by the object to produce an object wave directed at the image sensor. Further, the image sensor may be configured to determine an interference pattern between the reference wave and the object wave. A holographic image representing the object may be reconstructed based on the interference pattern.
