  • Patent number: 11499912
    Abstract: In order to avoid friendly fire incidents in the combat theater, novel covert identification systems and methods of identifying friendly forces are provided. The systems include at least a spectroscopic imaging device and a marker that interact with each other by using a synchronized, predetermined filter tuning sequence. The filter tuning sequence enables interacted photons to wavelength hop according to the predetermined tuning sequence. As a result, the covert identification system allows friendly forces to clearly identify each while avoiding detection by enemy forces that employ conventional broadband and night vision sensors.

  • Patent number: 11234584
    Abstract: Medical imaging systems for use in conjunction with an endoscope are described. Generally, the medical imaging system includes an illumination source configured to generate illuminating photons. The illuminating photons are transmitted to one or more filters configured to filter a first plurality of illuminating photons and generate a first plurality of filtered photons comprising a first passband wavelength and a second plurality of filtered photons comprising a second passband wavelength. A sample is then illuminated with the first plurality of filtered photons and the second plurality of filtered photons to generate a first plurality of interacted photons and a second plurality of interacted photons. One or more detectors are configured to detect the first plurality of interacted photons and the second plurality of interacted photons and generate one or more image data sets.

  • Publication number: 20210356795
    Abstract: A multi-conjugate filter (MCF) can be operated in both a single bandpass mode and a multiple bandpass mode. By applying different voltages to different channels of a MCF, the MCF can be used to filter light into (1) a single narrow spectral output or (2) a broad ranged “white light” spectral output.

  • Patent number: 7692776
    Abstract: A system and method of detecting explosive compounds located on a sample. The sample is irradiated with animal-safe ultra-violet radiation generating a fluorescence data set. A fluorescence database is searched based on the fluorescence data set in order to identify a known fluorescence data set. If the searching of the fluorescence database identifies a known fluorescence data set, an area of interest in the sample is identified based on the known fluorescence data set identified in the fluorescence database searching. The area of interest is irradiated with substantially monochromatic radiation to generate a Raman data set of the area of interest. A Raman database is searched based on the Raman data set in order to identify a known Raman data set. An explosive compound in the area of interest is identified based on the known Raman data set identified by searching the Raman database.
