Microcomputer-controlled optical apparatus for surveying, rangefinding and trajectory-compensating functions

摘要

A microcomputer controlled optical device for determining the distance to objects of known or estimable size which is programmed to control a plurality of associated electronic indicator elements the images of which are optically superimposed upon the image of an object the distance to which is to be determined. This device is useable on surveying instruments, riflescopes and the like and is controllable by the operator who selectively activates it by/with known data. Subsequently, the microcomputer interprets the data and selectively activates indicator elements representative of the relationship between the size of the object image and the distance to the object. Images of readouts are visible in the field of view which are activated and controlled by the microcomputer to indicate the computed distance to the object of interest in yards or meters.
