Abstract
In one exemplary embodiment, a shock-resistant night vision assembly is configured to detect a high-acceleration event, for example, resulting from a round or burst of high-caliber rifle fire. Upon detecting the event, a voltage such as a photocathode voltage is forced to an inactive or protective level and held there for approximately 50 ms, giving time for mechanical excursions of the microchannel plate to settle out. Damage from physical impact and electrostatic discharge may thus be mitigated.
