Spectral distribution emulation

摘要: A test arrangement for assessing the spectral energy distribution-determined response of a night vision device or other electro-optical apparatus. The provides library energy-distributed signals input scenes which may be selected to represent example typical extreme conditions expected during field use tested device. originate in an array transducer devices such as light emitting diode elements with each element proving limited wavelength component wide band composite optical signal received at port Each is arranged controlled electrically presence absence and also radiance intensity according needs scene being presented; control provided by manual controller programmed digital computer controlling apparatus logic array. include both infrared visible components. In addition signal, aspects performed data storage accomplished computer. disclosed especially suited performance verification systems laboratory environment prior similar systems. Military non-military uses are contemplated.
