This paper describes analytical and digital photogrammetric methods of a stereo pair of scanning electron microscope (SEM) photographs. Analytical method was applied to a triplet of stereo SEM photographs of an impression left by the diamond indenter of Vicker's hardness tester. The height error of the three dimensional measurement was ±5% and the precision is sufficient for surface shape analy...

Medical imaging is the technique and process used to create images of the human body or medical science. Digital image processing is the use of computer algorithms to perform image processing on digital images. Microscope image processing dates back a half century when it was realized that some of the techniques of image capture and manipulation, first developed for television, could also be ap...

Objective. The purpose of this study was to evaluate the efficiency of operating microscope compared with unaided visual examination, conventional and digital intraoral radiography for proximal caries detection. Materialsand Methods. The study was based on 48 extracted human posterior permanent teeth. The teeth were examined with unaided visual examination, operating microscope, conventional bi...

Across a broad range of medical disciplines, learning how to use an optical or light microscope has been a mandatory inclusion in the undergraduate curriculum. The development of virtual microscopy (VM) technology during the past 10 years has called into question the use of the optical microscope in educational contexts. VM allows slide specimens to be digitized, which, in turn, allows the comp...

In ULSI fabrication, the design rule scaled up to 0.25um and the complex multiple layer structure prevent from applying the traditional optical microscope of which resolution is about 0.4um. Considering the situation, we have developed a ULSI inspection system based on the scanning parallel confocal microscope. In this paper, we present the feature of the computer aided parallel scanning confoc...
