  • Patent number: 10966611
    Abstract: A system may include emitters configured to emit radiation at a first wavelength of electromagnetic (EM) radiation and a second wavelength of EM radiation towards a biological tissue, and receivers configured to receive responses to the first and second wavelengths of EM radiation after the wavelengths of EM radiation interact with the biological tissue. The system may also include a signal mixer unit configured to perform operations that include replicate and mix first signals representative of the responses to the first wavelength of EM radiation received by the receivers and second signals representative of the responses to the second wavelength of EM radiation received by the receivers to generate a set of spectro-spatial responses, replicate and mix the spectro-spatial responses to generate markers, and replicate and mix the markers and user-selected markers to output a sequence associated with characterization of the biological tissue.

  • Patent number: 10837897
    Abstract: There is disclosed a system and method for measuring the polarization of light which utilizes a spatially-varying polarization beam. This measurement is analyzed and improved using novel imaging methods and image processing methods on a digital signal processing (DSP) system to determine the polarization of light. Various embodiments are described which can measure light polarization, determine polarizing material distributions, determine the optical rotary dispersion of samples, and determine the circular dichroism of samples. In certain embodiments, the binding constants and binding activity of molecular samples can be achieved. Given its reduced complexity and size, the system may be configured to be portable such that the system may be used in various applications outside of a lab setting.

  • Patent number: 10530975
    Abstract: There is disclosed a novel system and method for multiview, multispectral, polarimetric, light-field, and high dynamic range imaging in a concurrent manner specifically capturing information at different spectral bands and light polarizations simultaneously. The present system and method is capable of (1) concurrent imaging of multiple spectral bands (including spectral bands beyond the visible region of the electromagnetic spectrum), proportional or greater than the number of filters used in the device, (2) concurrent imaging of multiple light polarizations (Stokes vectors), (3) acquiring images at different point-of-view of the same scene and/or object that allow for topographical reconstruction, (4) concurrent imaging of the multiple depth of fields that allow for light-field imaging, and (5) concurrent imaging of multiple simulated exposures of the detector that allow for high dynamic range imaging, all at the same time using a single sensor in the same imaging system enclosure.

  • Patent number: 9880390
    Abstract: There is disclosed a novel system and method for improving spectral resolution and signal-to-noise ratio of a captured spectrum by employing digital beam reforming, digital slicing, and digital multiplexing. In an embodiment, the method comprises: and entrance aperture for the light to enter the apparatus, a collimating element (refractive or reflective), a dispersive element (single- or multi-axis), a focusing element (refractive or reflective), and a linear or array detector for acquisition of the spectrum. The spectrum is then digitally beam reformed, digitally beam sliced to increase spectral resolution, and digitally beam multiplexed to increase the signal-to-noise ratio. In addition the disclosed invention is also capable of performing digital beam refocusing which means the optical focusing power can be chosen such that its performance surpasses the performance of any analog optical focusing element thereby further increasing the spectral resolution and the signal-to-noise ratio of the spectrum.
