Abstract
A cost considered arrangement for evaluating local illumination interference with operation of a night vision apparatus in for example the confines of an illumination inclusive aircraft cockpit. The evaluation is especially applicable to identifying interference between aircraft instrument lighting having infrared content for example, and night vision apparatus operation in the aircraft. The evaluation is cost is limited by use of a common household lamp night vision apparatus source calibrated with a common light measuring instrument operated at close range and with modification of the measured illumination through mathematical manipulation of the source operating distance to achieve the low light levels needed for night vision apparatus operation. A standard visual acuity chart and multiple operator interpretations of the chart resolutions achieved are included.
