A system for monitoring the condition of an optical device user with non-visible light includes a non-visible light source that is positioned to direct a beam of non-visible light onto an eye of the optical device user. A non-visible light sensor is positioned to receive non-visible light that is reflected off of the eye and is configured to generate a signal corresponding to either a level or an intensity of the received non-visible light. A processor is connected to the light sensor, and is configured to determine a condition of the eye including whether the eye is either not moving, closed without blinking or open without blinking for more than a pre-determined amount of time based upon signals received from the light sensor. Also disclosed herein is a method for monitoring the condition of an optical device user with non-visible light.

Apparatus and method for monitoring the condition of a night vision device user with non-visible light

A brightness tracking system for an optical device includes a first imager for viewing a target of interest, a second imager for viewing the same target of interest, and a photodiode circuit. The photodiode circuit (a) measures brightness levels of the target of interest received from the first imager, and (b) controls output brightness of the second imager, based on the measured brightness levels received from the first imager.

Brightness tracking light sensor

A target engagement system includes a night vision goggle system operating within a predetermined wavelength band, and a laser module projecting light onto a target, where the light operates at a wavelength that is outside of the predetermined wavelength band. Also included is a receive system for receiving the light reflected from the target and converting the light into a wavelength within the predetermined wavelength band. In this manner, the receive system provides the converted light to the night vision goggle system, and the night vision goggle system amplifies the converted light for viewing by a user. The receive system includes a clip-on device for removably attaching the receive system between the target and the night vision goggle system. The receive system includes an up-converting phosphor layer for up-converting the received light into a wavelength detectable by the night vision goggle system.
