Method and apparatus for testing visual acuity of a night vision imaging system using a visual target. A fixture arranges a mirror a first distance from the night vision imaging system and arranges the visual target a second distance from the mirror. A sum of the first distance and the second distance equals a target distance between the night vision imaging system and the visual target. The fixture includes a starlight generator that can illuminate the visual target with simulated starlight and/or moonlight that stimulates the night vision imaging system.
