On the fundamentals of optical scanning holography
نویسنده
چکیده
Optical scanning holography is a real-time holographic recording technique in which holographic information about a three-dimensional 3D object is acquired using a single two-dimensional active optical scan. Applications of the technique include optical scanning microscopy, pattern recognition, 3D holographic display, and optical remote sensing. This paper introduces the basics of optical scanning holography. © 2008 American Association of Physics Teachers. DOI: 10.1119/1.2904472

Optical Scanning Holography - Proceedings of the IEEE
This paper provides a tutorial on the principles of holography, followed by a review of a newly developed 3-0 imaging technique in which 3-0 optical information of an object can be extracted by a 2 -0 optical scan of the object. The technique is called optical scanning holography (OSH). In the context of optical scanning holography, we discuss some of its potential applications such as holograp...
متن کاملEdge Extraction Based on Aperture Synthesis in Optical Scanning Holography
Optical scanning holography (OSH) is an incoherent digital holography technique, with wide applications such as optical microscopy, remote sensing etc [1]. It uses a Fresnel zone plate (FZP) to record the volume information of an object by two-dimensional (2D) raster scanning. For optical image processing, it is highly desirable that the edge information can be extracted via reconstruction. Var...
متن کاملBlind sectional image reconstruction for optical scanning holography.
Optical scanning holography is a powerful holographic recording technique in which only a single two-dimensional scan is needed to record three-dimensional information. As in standard digital holography, for the reconstruction of a sectional image, the resulting data must then be postprocessed to obtain sectional content. We propose a blind sectional image reconstruction technique to automate t...

متن کاملReducing the acquistion time of optical scanning holography by compressed sensing
We propose a compressed sensing approach to improve the the acquisition time of optical scanning holography with a spiral trajectory. A two-sectional object is reconstructed with high fidelity by at least 5× speed improvement. OCIS codes: 110.1758, 090.1995, 100.3020
