A night vision device test arrangement for determination of spectral sensitivity field of view and other operating characteristics of night vision devices. The test arrangement includes a controllable array of radiant energy emitters such as narrow-band light emitting diode elements used to display a night vision device test pattern. The displayed test pattern may be located in the infrared or infrared and visible spectrum regions and may be altered by user command to have different configurations including different physical size, shape and array location and different spectral content. Control of the test pattern may employ a computer or a manual selection apparatus. The disclosed apparatus is especially suited to in-the-field GO/NO GO rapid performance verification of night vision device equipment. Military and non-military uses are contemplated.
