چکیده
Abstract We propose high-speed incoherent digital holography with a recording speed of 1,000 fps, which is designed for the three-dimensional (3D) motion-picture measurement moving objects high temporal resolution. adopt single-shot phase-shifting holography, polarization-imaging camera system, and palm-sized self-interference interferometer spatially temporally light, to implement system. High-speed four-dimensional (4D) (3D time) capability experimentally demonstrated, using constructed system set on wagon daily-use white-color light-emitting diode.

Phase-shifting digital holography.
A new method for three-dimensional image formation is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer. The method can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle than from conventional digital holography u...
متن کاملUncertainty-managed phase-shifting digital holography.
Phase-shifting digital holography is a digital measurement technology of a complex optical field profile that uses focal plane array detectors without the loss of bandwidth. It has been known that the accuracy of phase-shifting digital holography is limited mainly by the phase tolerance of reference. In this Letter, it is revealed that the uncertainty in an expected signal is highly dependent o...
متن کاملIncoherent Digital Holography: A Review
Digital holography (DH) is a promising technique for modern three-dimensional (3D) imaging. Coherent holography records the complex amplitude of a 3D object holographically, giving speckle noise upon reconstruction and presenting a serious drawback inherent in coherent optical systems. On the other hand, incoherent holography records the intensity distribution of the object, allowing a higher s...
متن کاملDigital spatially incoherent Fresnel holography.
We present a new method for recording digital holograms under incoherent illumination. Light is reflected from a 3D object, propagates through a diffractive optical element (DOE), and is recorded by a digital camera. Three holograms are recorded sequentially, each for a different phase factor of the DOE. The three holograms are superposed in the computer, such that the result is a complex-value...
متن کاملPhase-shifting Gabor holography.
We present a modified Gabor-like setup able to recover the complex amplitude distribution of the object wavefront from a set of inline recorded holograms. The proposed configuration is characterized by the insertion of a condenser lens and a spatial light modulator (SLM) into the classical Gabor configuration. The phase shift is introduced by the SLM that modulates the central spot (dc term) in...
