A New Photogrammetric Comparator Design,
Abstract
This paper describes a comparator believed to be unique in many respects. The laser interferometer permits a lightweight, compact design requiring less operating space and making the instrument very portable. The cost of the instrument is relatively low and the accuracy exceeds that required for most photogrammetric applications. The inclusion of an on-line programmable calculator enables relatively easy calibration of the system and permits near real time computations of the coordinates being measured. With additional programming, the instrument can perform other functions, such as the near real time computation of ground point positions, and any other photogrammetrically related task involving measurements and subsequent computations. The techniques employed in this new instrument represent significant progress in the design of photogrammetric comparators. They also hold great promise for a wide variety of applications in other similar devices.
