Abstract: An imaging system includes a photocathode, configured to be gated ON/OFF at a selected gating frequency, for converting photons from an object into electrons and selectively transmitting the electrons toward an imaging sensor. The imaging sensor is configured to receive the electrons and provide a rolling shutter read out of rows of pixels. The imaging sensor includes a variable well selectively set to charge the rows of pixels to a first intensity level during a first integration period and charge to a second intensity level during a second integration period. The second integration period is longer than an OFF time of the photocathode gating frequency. The first and second integration periods are equal to a frame duration of the imaging sensor, defining a number of frames per second, and the selected gating frequency of the photocathode is higher than the number of frames per second.

Abstract: An intensified solid-state imaging sensor includes a photo cathode for converting light from an image into electrons, an electron multiplying device for receiving electrons from the photo cathode, and a solid-state image sensor including a plurality of pixels for receiving the electrons from the electron multiplying device through a plurality of channels of the electron multiplying device. The solid-state image sensor generates an intensified image signal from the electrons received from the electron multiplying device. The plurality of channels are arranged in a plurality of channel patterns, and the plurality of pixels are arranged in a plurality of pixel patterns. Each of the plurality of channel patterns is mapped to a respective one of the plurality of pixel patterns such that electron signals from each of the plurality of channel patterns is substantially received by the single respective one of the plurality of pixel patterns.

Abstract: A fiber optic faceplate for protecting photosensitive material from high light levels which comprises an optical structure which optically acts like a solid window at low light levels, but which at least one of attenuates or diffuses light incident on the photocathode as a function of light amplitude. A method of operation and of manufacturing the faceplate, and devices incorporating the faceplate are also disclosed.

Abstract: An intensified hybrid solid-state sensor includes an imaging device comprising a solid-state sensor assembled with an image intensifier cathode, microchannel plate (MCP), and body envelope. This device combines the best functions of the image intensifier, good signal-to-noise ratio and high logarithmic gain, with the electronic read-out functions either of a Complementary Metal Oxide Semiconductor (CMOS) or charged coupled device (CCD). Applications for this invention are primarily night vision systems where good low light sensitivity and high gain are required.
