Abstract

For several years, inspection integrators have had the use of fiberscopes which are employed as borescopes for use in remote inspection applications. However, these are limited to RS170 performance in terms of throughput, sensitivity, and resolution. This paper reports on a new machine vision camera which is small in size (2 inches by 3/4 inches in the image plane) yet offers the resolution and throughput of a variable scan camera. This miniature light weight camera for machine vision can be placed in spaces where physical size and weight are limitations, such as at the end of remote manipulator arms used in automated assembly. A miniature line scan camera using a 1024 pixel line scanner is discussed which has the added feature that video data from multiple remote camera heads can be electronically combined and digitized at a central controller. This permits multiple views of the same object from cameras which can be placed in a space less than 3 cubic inches. This flexibility permits the ease of placement of cameras on the assembly line.
