An Apparatus for Aperture-Response Testing of Large Schmidt-Type Projection Optical Systems
An interpretation of the aperture-response concept as it applies to lenses or optical systems is followed by a description of an apparatus with which large Schmidt-type projection optical systems may be tested. The apparatus is adapted to present continuously the response curve on an oscilloscope, where it may be photographed against a grid for further study. The optical system may be tested for response to both radial and tangential line detail, in field zones that extend out to half the normal raster diagonal from the center.
