Abstract: The present disclosure relates to hermetic sealing of a device within a package or assembly. The sealable device is preferably a MEMS device. Surrounding the device is a first seal member that defines an internal cavity. The device can be positioned within the internal cavity, the extents of which defines a first seal region. A second seal member, and possibly others, is preferably positioned outside of the first seal member. The second seal member surrounds the first seal member a spaced distance from the first seal member to define a second seal region. Getter material is preferably placed within the first and second seal regions, and the first and second seal regions are sealed under vacuum pressure to provide a MEMS packaged assembly having a relatively low leak rate.

Abstract: A method of manufacturing a multi-layer image intensifier wafer includes fabricating first and second glass wafers, each having an array of cavities that extend between respective openings in first and second surfaces of the respective glass wafer; doping a semiconductor wafer to generate a plurality of electrons for each electron that impinges a first surface of the semiconductor wafer and to direct the plurality of electrons to a second surface of the semiconductor wafer, bonding a photo-cathode wafer to the first glass wafer; bonding the semiconductor wafer between the first and second glass wafers, and bonding the second glass wafer between the semiconductor wafer and an anode wafer (e.g., a phosphor screen or other electron detector). A section of the multi-layer image intensifier wafer may be sliced and evacuated to provide a multi-layer image intensifier.

Abstract: A light intensifier includes a semiconductor structure to multiply electrons and block stray particles. A thin gain substrate layer includes an electron multiplier region that is doped to generate a plurality of electrons for each electron that impinges on an input surface of the gain substrate layer and blocking structures that are doped to direct the plurality of electrons towards emission areas of an emission surface of the gain substrate layer. Respective ribs of a first plurality of ribs on the input surface of the gain substrate layer are vertically aligned with respective blocking structures, and respective blocking structures are vertically aligned with respective ribs of a second plurality of ribs at the emission surface. This alignment directs electrons along a path through the gain substrate layer to reduce noise. The support ribs provide mechanical strength to the gain substrate layer, improving robustness of the light intensifier while minimizing noise.

Abstract: A method of controlling the performance of a night vision device includes supplying, by a power supply, to a microchannel plate of a light intensifier tube, a control voltage that controls a gain of the microchannel plate, determining an amount of compensation to apply to the control voltage based on a change to the control voltage attributed to a change in temperature of an operating environment of the night vision device, adjusting the control voltage in accordance with the amount of compensation to obtain a compensated control voltage, and supplying, by the power supply, the compensated control voltage to the microchannel plate of the light intensifier tube. The method may further include determining whether the night vision device has been used for a predetermined amount of time, and only after that predetermined amount of time, is the method configured to supply the compensated control voltage.

Abstract: A night vision system along with an image intensifier tube having a microchannel plate and method of forming the microchannel plate are provided. The microchannel plate comprises a plurality of spaced channels extending through the microchannel plate, wherein each channel sidewall surface near the input face of the microchannel plate comprises a series of layers formed thereon. The input face of the microchannel plate, as well as the sidewall surfaces of each channel near the input surfaces, are configured with an electron backscatter layer arranged between a contact metal layer and a secondary electron booster layer. When formed partially into the channel openings near the input face, the electron backscatter layer and overlying secondary electron booster layer are configured circumferentially around the sidewall surfaces and extend radially inward toward a central axis of each channel.
