Adaptive optics by incoherent digital holography.
Adaptive optics in astronomical and other imaging systems allows compensation of aberrations introduced by random variations of the refractive index in the imaging path. I propose what I believe is a new type of adaptive optics system that dispenses with the hardware lenslet arrays and deformable mirrors of conventional systems. Theoretical and experimental studies show that wavefront sensing a...
متن کاملPhase-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 کاملPhase Conjugate Optics and Real-Time Holography
Nonlinear optical mixing can be used to perform a variety of new optical functions, as well as real-time holography. The theory and some of the first experiments are described.
متن کاملA Proposal for Astronomical Adaptive Optics by Incoherent Digital Holography
A new type of adaptive optics system is proposed for astronomical imaging. It replaces the wavefront sensing and modulation hardware pieces of conventional adaptive optics with numerical processing capabilities of digital holography of incoherent sources. OCIS codes: (010.1080) Active or adaptive optics; (090.1000) Aberration compensation; (090.1995) Digital holography; (110.0115) Imaging throu...
متن کاملPhase retrieval combined with digital holography
We present a new method for realand complex-valued image reconstruction from two intensity measurements made in the Fourier plane: the Fourier magnitude of the unknown image, and the intensity of the interference pattern arising from superimposition of the original signal with a reference beam. This approach can provide significant advantages in digital holography since it poses less stringent ...
