Abstract: A computer-implemented method includes controlling an instrument to measure a fluorescence emission spectrum of a sample including a first peak emission wavelength and at least a second peak emission wavelength, emitted in response to an excitation wavelength and controlling the instrument to measure an absorbance obtained at the excitation wavelength of the sample. The method may include determining, using the computer, a ratio of the measurements at either the second peak emission wavelength, or a sum of measurements at a plurality of peak emission wavelengths including at least the first peak emission wavelength and the second peak emission wavelength, to the first peak emission wavelength, and calculating, using the computer, a value for a quality parameter based on a combination of at least the ratio and the absorbance measurement. The method may include controlling an associated process based on the quality parameter.

Abstract: The present application in some embodiments relates to methods for reducing noise and/or clutter when measuring a spectrum, particularly but not only for OCT imaging. In some embodiments a light source is synchronized with a detector. For example a narrow band light source is synchronized with a narrow band detector. For example, the light source may scan over multiple frequency bands and/or the detector may be tuned to a frequency band synergetic to the band of the light source. For example the light source and detector may be tuned to overlapping narrow bands. Optionally the detector has a sensor set for each frequency band. Optionally some sensor sets are individually resettable. For example each set may have a reset circuit. For example, a sensor set for a band not currently being measured is deactivated.

Abstract: Methods and apparatus for video rate or near video rate quantitative imaging of tissue physiological and morphological properties from visible/NIR light spectral images obtain rapid multi-spectral reflectance images by illuminating with a series of spectra containing multiple narrow wavelength bands. An iterative light-transport based inversion algorithm may be applied for correcting the intensity of the spectral images from the geometry/coupling effect as well as from the scattering amplitude distortions. The method can produce video rate absorption as well as scattering spectral images that can be further analyzed very rapidly, using matrix-based rapid inversion algorithms to produce more detailed quantitative images containing information relevant to tissue physiology and morphology.

Abstract: An imaging system includes an imager housing having a primary aperture defining an optical axis. A primary lens is disposed over the primary aperture. A first focal plane array (FPA) is within the imager housing. A second FPA is within the imager housing.
