چکیده
Guy Indebetouw Virginia Polytechnic Institute and State University (Virginia Tech) Physics Department Blacksburg, Virginia 24061 Abstract. We propose an algorithm that can extract the depth location of a target from its complex hologram directly in optical remote sensing applications. The target is located in a 3-D space and its complex hologram is obtained by optical scanning holography. Once the target’s depth has been extracted, we can recover the image of the target from its hologram. © 2002 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.1476939]

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 کاملChange Detection in Urban Area Using Decision Level Fusion of Change Maps Extracted from Optic and SAR Images
The last few decades witnessed high urban growth rates in many countries. Urban growth can be mapped and measured by using remote sensing data and techniques along with several statistical measures. The purpose of this research is to detect the urban change that is used for urban planning. Change detection using remote sensing images can be classified into three methods: algebra-based, transfor...
متن کاملElectro-Optical Design of Imaging Payload for a Remote Sensing Satellite
Remote sensing using small spacecraft arising from multi-objective economic activity problems is getting more and more developed. These satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. The space borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given t...
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 کاملOn the fundamentals of optical scanning holography
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 scann...
