    Abstract: An electronic detection system includes an electronic device, a detector and a memory. The electronic device includes a circuit substrate, a plurality of photoelectric components, and a plurality of tunable current source circuits. Each photoelectric component has one or more peak emission wavelengths in response to a plurality of current values. The tunable current source circuits are disposed on the circuit substrate and electrically connected to the photoelectric components. The detector captures a feature value of a corresponding one of the photoelectric components. One or more lookup tables stored in the memory are based on the feature values and the current values of the photoelectric components. Each tunable current source circuit transmits an input current to a corresponding one of the photoelectric components in response to the lookup table(s) to perform a selected peak emission wavelength.

    Abstract: Embodiments are disclosed relating to a refractively-scanning interferometer comprising an aperture that receives an incident light beam at a receiving angle, a beam splitter configured to split the incident light beam into a first beam and a second beam, a first and a second reflector arranged to reflect the first beam and second beam, respectively, towards a combining optical element, and a refractive Optical Path Difference (rOPD) assembly interposed between the beam splitter and the first reflector, wherein the rOPD Assembly refracts the first light beam an even number of times with induced phase discrepancy being a vector sum of a first phase discrepancy induced by a first refraction and a second phase discrepancy induced by a second refraction, the rOPD Assembly being configured such that the first phase discrepancy is substantially opposite in direction to the second phase discrepancy, a portion of the first and second phase discrepancies cancelling one another out to decrease magnitude of the phase discrepancy.

    Abstract: An interferometer for use in remote sensing systems includes a beam splitter that separates an input wave into a reflected wave, which travels along a first optical path within an upper interferometer arm, and a transmitted wave, which travels along a second optical path within a lower interferometer arm. The reflected and transmitted waves are subsequently recombined by the beam splitter for imaging onto a sensor. A highly dispersive element is incorporated into at least one of the pair of interferometer arms. Due to anomalous dispersion, a frequency shift in a wave transmitted through a dispersive element changes the optical path length within its corresponding arm. As a result, the recombined wave produces an interference pattern with a measurable phase change that can be utilized to calculate the original frequency shift in the input wave with great precision and potential sub-Hertz sensitivity.

    Abstract: A Fourier Transform Spectrometer (“FTS”) system includes a Fizeau FTS having a plurality of sub-collecting elements, adjacent ones of which are separated by a gap distance, and at least one of which has an adjustable optical path. The FTS system further includes a Michelson FTS having an adjustable optical path. The FTS system further includes one or more processors configured to select spectral data collected by the Fizeau FTS corresponding to spatial frequencies for which the Fizeau FTS has a modulation transfer function (“MTF”) value above a first threshold level, to select spectral data collected by the Michelson FTS corresponding to spatial frequencies for which the Michelson FTS has a MTF value above a second threshold level, and to combine the selected spectral data from the Fizeau FTS with the selected spectral data from the Michelson FTS.
