VIEW FINDER FOR OPTICAL RANGING

摘要

A telemetry system comprises a video camera of the kind such that, as a result of the substantial magnification provided, it is necessary also to use a collimating video camera. The use of the collimating camera is rendered possible by mirrors which enable the telemetry operation to be carried out on a virtual object. The system is of especial value in installations which are hostile and inaccessible to human beings.
