WIDE DYNAMIC RANGE VIDEO CAMERA ABSTRACT A television camera apparatus wherein bright objects are attenuated to fit within the dynamic range of the system while dim objects are not receives linearly polarized light from an object scene, the light being passed by a beam- splitter and focused on the output plane of a liquid crystal light valve oriented such that, with no excitation from a cathode ray tube, all light is rotated 90° and focused on the input plane of a video sensor. The light is then converted to an electrical signal, which is amplified and used to excite the CRT. The resulting image is collected and focused onto the light valve, which rotates the polari- zation vector of each light increment to an extent proportional to the light intensity from the CRT. The over- all effect is to selectively attenuate the image pattern focused on the sensor.
