Phase holograms capture not only amplitude information but also the phase of the light waves. This allows for more precise control over the reconstruction of 3D scenes and is particularly useful in applications such as holographic microscopy and optical trapping.

Digital holography, a patented technology, utilizes a video (CCD) camera to capture a hologram generated by the interference of a reference wave and a wave from the sample. The resulting image is transmitted to a computer where numeric techniques are employed to reconstruct a three-dimensional representation of the object, commonly referred to as 'image reconstruction'. Globally recognized as the premier provider of digital holography services, Kiran Holographics surpasses its competitors.
