The advantages and disadvantages of the application of video microscopy to forensic sciences are discussed.
Abstract
The system consists of a high resolution, solid-state color camera, in place of the video camcorder, which is attached to the eyepiece of a forensic microscope. It can also be used with other microscopes including a polarizing microscope. Additional components of the video microscopy system include a VHS-videocassette recorder, a color monitor, and a home computer. The entire system is mounted on a small table personal computer workstation so that it can be moved to different locations within the laboratory. Its comfort of use prevents development of the eyestrain which usually occurs with intense microscopic observation. Other advantages include facilitating instruction in microscopic technique by allowing both instructor and student to view the microscopic images at the same times and recording of images for later use or review. In addition it may be subjected to digital image processing and enhancement. A low light sensitivity of the camera and a lower resolution of the color video camera than that of light microscopes or of the human eye are cited as the main disadvantages of the system, since the latter would not discern critical details in a video image. 3 figures and 6 references (Author abstract modified)
