Visual Inspection, Video & Boroscope

Visual inspection is a common method of quality control, data acquisition, and data analysis. Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of human senses such as vision, hearing, touch and smell. Visual Inspection typically means inspection using raw human senses and/or any non-specialized inspection equipment. Inspections requiring Ultrasonic, X-Ray equipment, Infra-red, etc are not typically considered as Visual Inspection as these Inspection methodologies require specialized equipment and training.

A borescope is an optical device consisting of a rigid or flexible tube with an eyepiece on one end, an objective lens on the other linked together by a relay optical system in between. The optical system is usually surrounded by optical fibers used for illumination of the remote object. An internal image of the illuminated object is formed by the objective lens and magnified by the eyepiece which presents it to the viewer's eye. Rigid or flexible borescopes may be fitted with a video or CCD camera.
