1 September 1975 New Solutions To The Depth Of Field Problem In Flight Simulation Image Pick-Up Devices

In flight simulation visual systems in which an image is picked up by a CCTV camera probe from a model terrain, there is a well known problem in focusing on the model surface across the whole imaged area, particularly as the probe entrance pupil approaches close to the model. The problem will increase as we try both to improve the resolution of the CCTV camera and probe and to reduce the scale of the terrain model, so that conventional techniques of moving and tilting lenses within the probe optics will not be sufficiently powerful for some desirable probe systems. There is a closely-related problem in correction of optical aberrations of probe systems for a wide range of object conjugate distances. The problems are assessed in relation both to normal TV systems and to laser TV systems. A novel form of tilt-lens system is described.*
