Abstract: According to some embodiments, a Micro Wideband Spectroscopic Analysis Device (MWSAD) is designed to operate from the visible to the far infrared. The MWSAD is the first unified platform to implement nearly all kind of molecular spectroscopy. This design is based on combining/integrating Diffractive Focusing Element (DFE) such as Fresnel lens/Zone plate with wide and finite range tuning devices. The wide range tuning devices are tunable lenses and/or a long stroke linear motor. The finite tuning devices are micro pinhole controlled by MEMS/PZT actuator. The MEMS/PZT actuator is used for finite tuning the micro pinhole location across the chromatic focuses of the Fresnel lens/DFE. The long stroke linear motor is used for wide range tuning the pinhole location across the chromatics focuses. The tunable lens is used for wideband tuning the chromatics focuses locations within the micro pinhole.

Abstract: A high resolution, non-scanning system for microscopy and/or tomography whereby a broad non-focused input image transmitted through a medium such the human body is processed, in contrast with a focused scanning beam. A high pass filter provides high sensitivity, and a high magnification feedback loop magnifier having reduced lens aberrations is also provided. A zoom lens focuses the input image such as a tumor at different planes within the medium. Image processing systems for correction via a back-propagation algorithms followed by a two-dimensional (2-D) deflection sensor and a 2-D Demultiplexer is employed to produce separate phase and amplitude image signals that are then mixed and applied to a display yielding three dimensional tomographic images. Novel two demultiplexers for calculation amplitude and phase images are disclosed based on a smart pixelated array, a tunable grating, and a two-probe beam hologram, each beam having two different wavelengths or two different modulations.

Abstract: A matched amplification correlator transforms input images projecting a real time hologram upon a holographic storage device and a spatial light modulator, optically coupled to the storage device, modulates the hologram with a correlation filter, and the modulated signal is Fourier transformed to produce an output correlation signal. Alternatively, Fourier transforms of beams bearing the signals to be correlated are projected upon a beam controlled semi-conductor absorption modulator for selectively switching the Fourier transform of the noisy cluttered image through the device, and a spatial light modulator, modulates the hologram with a correlation filter, and the transform produces an output correlation signal. These compact adaptive, noise robust correlators can be made as small as one cubic centimeter. In a correlation system of exemplary figure one, nearly one hundred million correlations per second (0.1 Ghz) are possible. Front end components of the correlators can be used to clean noisy images.

Abstract: An angularly multiplexed store contains filters derived from prior examination of input image reference samples, a spectrum analyzer produces spectral data representing the frequency spectrum of the input image under examination, a computer produces an encoded map of the spectral data representing the input image frequency spectrum. The encoded map is transformed, inputted into the store while close match spectral correlation light beams emerge from the multiplexed store, each having an emerging angle associated with that filter within the multiplexed store producing a close match with the first transform. An array of light beam detectors and a display present images having colors that indicate the nature of the input image such as a type of cancer. An associated memory-retro-reflector arrangement displays characters naming the materials making up the input image such as types of abnormal tissue.

Abstract: A design of a compact, adaptive, noise robust, and ultra fast correlator is presented. For realizing a correlator with these features the following design steps are taken: For noise robustness a matched amplification-switching is implemented prior to the correlation process. For structure compactness, a lens is integrated in the input plane of the correlator, and a slap of multi devices is integrated in the Fourier plane. The slap consists of a spatial light modulator, a lens, a polarizer, and a light controlled by light modulator for performing matched amplification- switching. These integration procedures allow to built a correlator as small as one cubic cm3. The additional features allow this correlator to perform 105 correlation/sec.
