Abstract: A method for processing light energy is provided that includes receiving a plurality of photons reflected by an object and generating sensor data that is based a portion of the plurality of photons received. The sensor data is processed in older to generate processed sensor data. A segment of the processed sensor data that directly corresponds to the portion of the plurality of photons is displayed such that the segment may be viewed.

Abstract: A night vision device (10) includes an image intensifier tube (14) which includes a photocathode (22) responsive both to white light and to infrared light to release photoelectrons. The photocathode (22) is particularly sensitive to infrared light at the 980 nm wavelength, and has desirable spectral response characteristics.

Abstract: An integrated night vision device and laser range finder (10) provides both night-time and day-time imaging by use of an image intensifier tube (14), as well as providing laser range finding operations both day and night. In a laser range finder mode of operation the device (10) projects a pulse of laser light into a scene being viewed, and a power supply and laser range finder circuit (62) of the device (10) temporarily utilizes the image intensifier tube (14) as a sensor to detect reflected laser light. During laser range finding, imaging is cut off for a very short time interval. During imaging operations, the power supply and laser range finder circuit (62) operates the image intensifier tube (14) in a unique way to provide both improved automatic brightness control (ABC) and improved bright-source protection (BSP). The ABC and BSP functions are coordinated with the laser range finding function.
