Review of three-dimensional holographic imaging by Fresnel incoherent correlation holograms

Abstract

Holographic imaging offers a reliable and fast method to capture the complete 3-D information of the scene from a single perspective. We review our recently proposed single-channel optical system for generating digital Fresnel holograms of 3-D real-existing objects illuminated by incoherent light. In this motionless holographic technique, light is reflected, or emitted, from a 3-D object, propagates through a spatial light modulator (SLM), and is recorded by a digital camera. The SLM is used as a beam-splitter of the single-channel incoherent interferometer, such that each spherical beam originated from each object point is split into two spherical beams with two different curve radiuses. Incoherent sum of the entire interferences between all the couples of spherical beams creates the Fresnel hologram of the observed 3-D object. When this hologram is reconstructed in the computer, the 3D properties of the object are revealed.

Spatio‐Spectral‐Temporal Imaging of Fast Transient Phenomena Using a Random Array of Pinholes

“…In general, holography techniques are avoided for many imaging applications partly due to the bulky interferometer configuration and partly due to the need for multiple camera shots to reconstruct a scene without the twin image and bias terms. [ 16,17 ] In the recent years, there has been rapid developments in the area of incoherent lensless imaging and holography techniques. [ 18–22 ] While the method described in the study by Isikman et al [ 18 ] is truly lensless with no element in between the object and the image sensor, the previous studies [ 19–22 ] use a coded phase mask or a diffuser in between the object and the image sensor.…”

Interference and polarization beating of independent arbitrarily polarized polychromatic optical waves

“…The area of applications of the interference phenomenon is wide, ranging from sensors of picometer-amplitude vibrations [2] to detection of cosmic gravitational waves [3]. Many important scientific and technological applications of optical interferometry are found in optical communication and information processing [4,5], laser cavity designs [6,7], correlation-based imaging [8][9][10], spectroscopy [11,12], and metrology [13].…”

Partially coherent lensfree tomographic microscopy [Invited]

“…Multivariate statistical analysis and feature extraction techniques have also been demonstrated as computational means of achieving 3D imaging from a single-shot hologram recorded using coherent or partially coherent light [36–38]. Moreover, 3D holographic imaging has also been extended to fluorescent imaging modalities through the use of spatial light modulators without the need for mechanical scanning [39–41]. …”
