  • exposure In optics, the total radiant energy incident on a surface-per-unit area. It is equal to the integral over time of the radiant flux density. Also known as radiant exposure.
  • photoelectric control The control of an instrument or electrical circuit by the current produced by varying radiation incident to a photoelectric cell.
  • brightness control The manual shifting bias control of a cathode-ray tube that determines both the average brightness and the contrast of a picture.
  • photoelectric exposure meter A device consisting of a microammeter, a photovoltaic cell and a battery. It is used for the measurement of scene brightness and the determination of correct exposure for photographic processes.
