摘要： Disclosed is an apparatus (100) for measuring time-resolved optical spectrum, the apparatus comprising a light source (102) for generating a pulse of light towards a target (110). The apparatus further comprises a sensor arrangement (118, 200) for collecting the emitted optical radiation, forming and manipulating the emitted optical radiation and measuring the intensity of the optical radiation, and a controller (120, 228) operatively coupled to the light source and the sensor arrangement. The sensor arrangement comprises at least one optical delay element (212, 214, 402, 404, 406) to provide a time delay to a first portion (208, 508, 604) of the emitted optical radiation (210, 302, 412, 706). The sensor arrangement further comprises an optical spectral disperser (220) to split the delayed first portion and the second portion of the emitted optical radiation into dispersed radiation having a plurality of wavelengths, and a sensor element (226, 314, 426, 612) configured to receive each wavelength of the dispersed radiation on a different spatial region thereof, and to measure the light intensity associated with each wavelength of the dispersed radiation. Furthermore, the controller is operable to collect the amount of light intensity associated with each wavelength of the dispersed radiation measured by the sensor element to form a time-resolved optical spectrum.

摘要： Configurable handheld biological analyzers and related biological analytics methods are described for identification of biological products based on Raman spectroscopy. A biological classification model configuration is loaded into a computer memory of a configurable handheld biological analyzer having a processor and a scanner. The biological classification model configuration includes a biological classification model configured to receive a Raman-based spectra dataset defining a biological product sample as scanned by the scanner. A spectral preprocessing algorithm is executed to reduce a spectral variance of the Raman-based spectra dataset. The biological classification model identifies a biological product type based on the Raman-based spectra dataset and further based on a classification component selected to reduce at least one of (1) a Q-residual error or (2) a summary-of-fit value of the biological classification model. The biological classification model configuration is transferrable to and loadable on other configurable handheld biological analyzers.
