摘要： An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The transparent overlay display is a borderless display in which the active area extends to at least one edge of the display. Data-handling circuitry is arranged within the active area, rather than being arranged along a border of the display. The data-handling circuitry may be fabricated in the active area of the display by fabricating it below opaque pixel regions that generate the display light. This borderless configuration allows partial overlap with the intensified image by eliminating opaque borders in which the data-handling circuitry is fabricated. This borderless configuration helps to minimize size, weight, and power by reducing the size of the display and eliminating the need for bulky beam splitters.

摘要： A photomultiplier tube (PMT) detector assembly includes a PMT and an analog PMT detector circuit. The PMT includes a photocathode configured to emit an initial set of photoelectrons in response to an absorption of photons. The PMT includes a dynode chain with a plurality of dynodes. The dynode chain is configured to receive the initial set of photoelectrons, generate at least one amplified set of photoelectrons, and direct the at least one amplified set of photoelectrons. The PMT includes an anode configured to receive the at least one amplified set of photoelectrons, with a digitized image being generated based on a measurement of the final amplified set of photoelectrons. The digitized image is corrected by applying an output of the signal measured by the analog PMT detector circuit to the digitized image.

摘要： A photomultiplier tube includes a semiconductor photocathode and a photodiode. Notably, the photodiode includes a p-doped semiconductor layer, an n-doped semiconductor layer formed on a first surface of the p-doped semiconductor layer to form a diode, and a pure boron layer formed on a second surface of the p-doped semiconductor layer. A gap between the semiconductor photocathode and the photodiode may be less than about 1 mm or less than about 500 μm. The semiconductor photocathode may include gallium nitride, e.g. one or more p-doped gallium nitride layers. In other embodiments, the semiconductor photocathode may include silicon. This semiconductor photocathode can further include a pure boron coating on at least one surface.

摘要： In the photocathode, an underlayer made of a crystalline material containing La2O3 is provided between a supporting substrate and a photoelectron emission layer, and is in contact with the photoelectron emission layer. Therefore, for example, at the time of heat treatment in a manufacturing process of the photocathode, dispersion to the supporting substrate side of an alkali metal contained in the photoelectron emission layer is suppressed. Further, it is assumed that this underlayer functions so as to reverse the direction of, out of photoelectrons e— generated within the photoelectron emission layer, photoelectrons traveling toward the supporting substrate side to the side opposite thereto.

摘要： A photoelectric emission surface which is excellent in stability and reproducibility of photoelectric conversion characteristics and has a structure capable of obtaining a high photosensitivity is provided. A predetermined voltage is applied between an upper surface electrode and a lower surface electrode by a battery. Upon application of this voltage, a p-n junction formed between a contact layer and an electron emission layer is reversely biased. A depletion layer extends from the p-n junction into the photoelectric emission surface, and an electric field is formed in the electron emission layer and a light absorbing layer in a direction for accelerating photoelectrons. When incident light is absorbed in the light absorbing layer to excite photoelectrons, the photoelectrons are accelerated by the electric field toward the emission surface. The photoelectrons obtain an energy upon this electric field acceleration, and are transitioned, in the electron emission layer, to a conduction band at a higher energy level, and emitted into a vacuum.
