    Abstract: An imaging system includes a plurality of optical sensors arranged on an integrated circuit in an array with a plurality of rows and a plurality of columns. The system includes an interface communicating with the plurality of optical sensors, memory storing operational instructions and processing circuitry configured to sample an image using the plurality of optical sensors in a first mode and sample at least a portion of the image sequentially on a row-by-row basis at a predetermined sampling rate in a second mode to produce row by row sample outputs. The processing circuitry is further configured to initiate sampling at least some rows of the plurality of rows of optical sensors using different time stamps.

    Abstract: A system for non-invasively interrogating an in vivo sample for measurement of analytes comprises a pulse sensor coupled to the in vivo sample for detect a blood pulse of the sample and for generating a corresponding pulse signal, a laser generator for generating a laser radiation having a wavelength, power and diameter, the laser radiation being directed toward the sample to elicit Raman signals, a laser controller adapted to activate the laser generator, a spectrometer situated to receive the Raman signals and to generate analyte spectral data; and a computing device coupled to the pulse sensor, laser controller and spectrometer which is adapted to correlate the spectral data with the pulse signal based on timing data received from the laser controller in order to isolate spectral components from analytes within the blood of the sample from spectral components from analytes arising from non-blood components of the sample.

    Abstract: The disclosure provides improved processing of optical data by identifying anomalous signals in the electrical data representing the optical data. The improved processing can also include modifying the identified anomalous signal data to provide a truer representation of the optical data. The disclosed processing can be used by various systems and apparatuses for processing spectral data corresponding to the optical data. The improved processing can be used to improve the monitoring of semiconductor processes and, therefore, improve the overall semiconductor processes. In one example, a method of processing spectral data includes: (1) receiving temporally separated spectral data samples, and (2) identifying one or more anomalous signals in an intermediate one of the temporally separated spectral data samples based on at least one preceding and at least one subsequent ones of the spectral data samples.

    Abstract: A device may receive a master data set for a first spectroscopic model; receive a target data set for a target population associated with the first spectroscopic model to update the first spectroscopic model; generate a training data set that includes the master data set and first data from the target data set; generate a validation data set that includes second data from the target data set and not the master data set; generate, using cross-validation and using the training data set and the validation data set, a second spectroscopic model that is an update of the first spectroscopic model; and provide the second spectroscopic model.

    Abstract: In some implementations, a device may identify, based on spectroscopic data, a pseudo steady state end point indicating an end of a pseudo steady state associated with the blending process. The device may identify a reference block and a test block from the spectroscopic data based on the pseudo steady state end point. The device may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate a statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block. The device may determine whether the blending process has reached a steady state based on the statistical detection signal.
