Abstract: A spectrometer system may be used to determine one or more spectra of an object, and the one or more spectra may be associated with one or more attributes of the object that are relevant to the user. While the spectrometer system can take many forms, in many instances the system comprises a spectrometer and a processing device in communication with the spectrometer and with a remote server, wherein the spectrometer is physically integrated with an apparatus. The apparatus may have a function different than that of the spectrometer, such as a consumer appliance or device.

Abstract: Provided is a spectrophotometer having a sample container 30, a light-source unit 10 for casting measurement light into the sample container 30, a photodetector 40 for detecting light obtained from the sample container 30 illuminated with the measurement light, a light separator 20 placed between the light-source unit 10 and the sample container 30, an A/D converter 50 for converting detection signals from the photodetector 40 into digital signals, and an A/D conversion time controller 65 for controlling an A/D conversion time in the A/D converter 50. The A/D converter 50 receives, for each A/D conversion time, detection signals sequentially produced by the photodetector 40, and sequentially outputs values corresponding to the amounts of signals received. The A/D conversion time controller 65 controls the A/D conversion time at five times (preferably, ten times) the cycle of commercial power supplies or longer during wavelength-correctness validation of the light separator 20.

Abstract: Described self-referencing cavity enhanced spectroscopy (SRCES) systems and methods are tailored to acquiring spectra in a middle regime, in which signals are lower than optimal for conventional absorption spectroscopy, and absorption is higher than optimal for cavity ring-down spectroscopy (CRDS). Longitudinal mode resonance spectral peaks are analyzed individually to extract intensity ratios (e.g. maximum to minimum) and/or curve-fitting parameters, obviating the need to measure or precisely control the input light intensity.

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.
