    Abstract: An apparatus and method disclosed herein can be utilized in all DMA-based optical systems, such as imaging and projection devices, in order to improve light efficiency and brightness by a significant factor and maintain good contrast. This feature is especially important in night vision systems and other low light applications. A means is provided of masking a designated area of light collected by the system objective lens in order to eliminate light collected from “flat” or “off” state micromirrors that would degrade the image quality produced. The masked objective lens, with a larger aperture, enhances the light collection from micromirrors in the “on” state only.

    Abstract: An improved intensity control system for an intensified imaging system allows continuous viewing through an intensified imaging system while protecting saturated areas from the negative effects of overexposure. A micromirror array (MMA) is used in conjunction with associated optics to control the intensity incident on the image intensifier. Control circuitry determines if pixel intensity is above or below the preset threshold level. If above, the corresponding elements of the MMA array will deflect the incident light in that specific area thereby eliminating saturation of the pixels. The rest of the image is maintained for continuous viewing. A continuous feedback loop monitors the intensity levels of pixels and actively controls the incident light using the MMA.

    Abstract: An improved optical pressure sensor determines the pressure of the fluid to be monitored by the deflection of a diaphragm in the pressure chamber of the sensor which has an inlet from the measured vessel. The deflection of the diaphragm is determined by monitoring the interference of diode light reflected from the diaphragm and a silicon grating structure superimposed over the diaphragm, at critical positions. Intensity detectors are placed at critical positions such as the specific orders of the diffraction grating to measure the interference intensity of the reflected light. The interferometric accuracy with which the pressure measurement is made with the present invention far exceeds that obtained with optical pressure sensors described in the prior art.

    Abstract: An improved tunable diode laser is capable of fast digital line selection over a broad wavelength spectrum, and uses no moving parts. A focusing element, such as a mirror or a lens, used in combination with a micromirror array serves as the retroreflector in a typical Littman-Metcalf laser cavity. This configuration provides arbitrary, simultaneous, and/or sequential line selection capability over a very broad wavelength range. The use of an individually-controllable micromirror array eliminates the high precision mechanical motion of a grating element and improves the overall durability and ruggedness of the device. The present invention can be integrated into any diode laser and has significant application in spectroscopy.

    Abstract: A tunable laser system where incoming light is separated into wavelength separated light; the separated light is focused into a plurality of single wavelength focal spots. The laser system includes a locally controllable reflectivity array having a plurality of individually controllable localized reflective elements corresponding to and reflecting one of the plurality of focal spots. A wavelength filter substantially allows wavelengths of the incoming light separated by a specified frequency to emerge as filtered light, while substantially barring other wavelengths. The separated light includes this filtered light. An elongation element for elongates the wavelength separated light into a plurality of elongated single wavelength focal spots. The locally controllable reflectivity array includes a plurality of sets of a plurality of individually controllable localized reflective elements, each set corresponding to and reflecting one of the elongated single wavelength focal spots.
