Abstract: A target-seeking-and-tracking system featuring hyperspectral sensing performed by a tunable filter and an infrared focal plane array is programmable to collect and process several hyperspectral bands of infrared radiation emanating from a target scenery. The programming is done by tuning the filter from time to time to collect several hyperspectral bands containing image data corresponding to several objects of interest in the scenery. The image data is further processed in the target recognition unit to identify the objects and aid in the selection and tracking of a particular target object for the ultimate goal of accurate destruction of the object. The programmability of hyperspectral sensing provides a degree of countermeasures immunity by allowing several bands to be combined to achieve the best signal-to-clutter ratio.

Abstract: A spectrometer that provides the ability to combine the advantages of high resolution, compactness, ruggedness, and low-power consumption of Fabry-Perot (FP) tunable filter spectrometer, with the multi-channel multiplexing advantage of FT and/or grating/detector array. The key concept is to design and operate a tunable FP filter in a multiple-order condition. This filter is then followed by a “low-resolution” fixed grating, which disperses the filtered n-order signal into a preferably matched N-element detector array for parallel detection. The spectral resolution in this system is determined by the FP filter, which can be designed to have very high resolution. The N-order parallel detection scheme reduces the total integration or scan time by a factor of N to achieve the same signal to noise ratio (SNR) at the same resolution as the single channel tunable filter method. This design is also very flexible, allowing spectrometer systems with appropriate order N to thereby optimize the system performance for spectral resolution and scan integration time. In addition to the significant reduction in scan integration time, there are two other advantages to this approach. The first, because the FP tunable filter is designed and operated under n-orders, the fabrication tolerances of the FP filter cavity and operating conditions are significantly loosened.

Abstract: A scanning tunable detection system and related method for analyzing samples includes a source of time varying excitation signals and a tunable optical filter for selectively transmitting time-varying optical signals emanated from a sample following irradiation with the time varying excitation signals. A detector is provided for converting the time-varying optical signals to electrical detection signals.
