The description and luminous calibration of cathode ray oscilloscope visual displays

摘要: A description of a CRO display should include descriptions of: (1) typical contents (e.g., photograph), (2) output parameters refresh rate), and (3) luminous measurements. Luminous calibrations are unorthodox because displays discontinuous in space time, they sources, not reflectors, light. The appropriate quantities luminousintensity the integral intensity (luminous directional energy, LDE); measurements ofLDE per point unit line length. simple calibration procedure is described, formulas relating these to luminances given.
