    摘要: A semiconductor detector has a tunable spectral response. These detectors may be used with processing techniques that permit the creation of “synthetic” sensors that have spectral responses that are beyond the spectral responses attainable by the underlying detectors. For example, the processing techniques may permit continuous and independent tuning of both the center wavelength and the spectral resolution of the synthesized spectral response. Other processing techniques can also generate responses that are matched to specific target signatures.

    摘要: Exemplary embodiments provide an infrared (IR) retinal system and method for making and using the IR retinal system. The IR retinal system can include adaptive sensor elements, whose properties including, e.g., spectral response, signal-to-noise ratio, polarization, or amplitude can be tailored at pixel level by changing the applied bias voltage across the detector. “Color” imagery can be obtained from the IR retinal system by using a single focal plane array. The IR sensor elements can be spectrally, spatially and temporally adaptive using quantum-confined transitions in nanoscale quantum dots. The IR sensor elements can be used as building blocks of an infrared retina, similar to cones of human retina, and can be designed to work in the long-wave infrared portion of the electromagnetic spectrum ranging from about 8 μm to about 12 μm as well as the mid-wave portion ranging from about 3 μm to about 5 μm.

    摘要: The present invention includes methods for the reduction of speckle noise in an image and methods for segmenting an image. Each of the methods disclosed herein includes steps for analyzing the uniformity of a pixel within a plurality of pixels forming a portion of the image and, based on the uniformity of the intensity of the plurality of pixels, adjusting and/or replacing the pixel in order to produce a speckle-noise reduced image, a segmented image, or a segmented and speckle-noise reduced image. The methods of the present invention can employ for example conditional probability density functions, nonlinear estimator functions, convex energy functions and simulated annealing algorithms in the performance of their respective steps.

    摘要: Exemplary embodiments provide microscope devices and methods for forming and using the microscope devices. The microscope device can include a light emitter array with each light emitter individually addressable to either emit or detect light signals. Magnified images of a sample object can be generated by a reflection mechanism and/or a transmission mechanism using one or more microscope devices in an imaging system. Real-time computer control of which microscope pixels are viewed can allow the user to digitally replicate the “fovea” function of human vision. Viewing an object from both sides in the double-sided microscope system and from multiple pixel positions can allow the microscope to reconstruct pseudo-3D images of the object.
