Abstract:

In meeting requirements for ever larger field angles in training devices, such as for helicopter pilots, tank drivers, etc., a design study of a lens system for panoramic imagery was made. Two designs have been brought to the point where their manufacture can commence Design A with 50mm image diameter, F5, elevation angles of 60 and -30 deg Design B with 95mm image diameter, F10, and elevation angles of 28 and -15 deg. The optical system consists of two protected confocal hyperboloidal mirrors acting as a reversed Gallilean telescope, followed by a refractive system. The system can be used as a camera and as projection lens it has been designed to withstand the heat of a high power arc lamp. Resolution is about 40 linesmm, but there is room for further improvements.
