Abstract: In a method of using a polarimeter for improved mapping and perception of objects on the ground, the polarimeter records raw image data to obtain polarized images of an area. The raw image data is processed to form processed images. The processed images are enhanced, and objects are detected and tracked. The polarimeter may be in a vehicle on the ground or in the air.

Abstract: A method for detecting and tracking aerial objects and vehicles comprises recording raw image data using a polarimeter to obtain polarized images of the sky. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object.

Abstract: A method using Long Wave Infrared Imaging Polarimetry for improved mapping and perception of a roadway or path and for perceiving or detecting obstacles comprises recording raw image data using a polarimeter to obtain polarized images of the roadway or area. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object. Further, the vehicle may take evasive action based upon the presence of an object in the roadway.

Abstract: A mounting process/device for mounting and alignment of micro optical electro-mechanical systems (MOEMS) elements and/or devices. The mounting process/device can be obtained by attaching at least one optical element onto a mounting system, which contains an embedded optical element. The attached optical element(s) are aligned with respect to the embedded optical element.

Abstract: A master wafer is replicated by creating a mold by plating a nickel electroform on a surface of a silicon wafer. Thereafter, a child wafer is prepared with a layer of photoresist or similar material that is compatible with plasma-etching techniques. Thereafter, the mold shape is transferred to the photoresist through compression molding, thereafter the child wafer is etched.

Abstract: Multi-levels are etched into silicon. The levels are etched through a combination of crosslinking photoresist, multiple photoresist patterning and development, wet etching and/or dry-etching. RIE, DRIE, and other etch techniques can be used during different steps. The multilevel structure may thereby be produced at commercially acceptable production rates allowing the method of the present application to be used in volume production of multilevel structures.

Abstract: A laser pulse communication system that orients a polarization analyzer to a state determined based on received laser pulses. The oriented state of the polarization analyzer allows a transceiver to obtain a replica of the transmitted laser pulses that are unbroadened by multiple reflections caused by inter-transceiver media. The obtained replica, therefore, has an enhanced signal to noise ratio.
