Abstract: The disclosure provides features for improved processing of optical data by identifying and characterizing stationary and transient signals in the electrical data representing the data collected from an optical sensor of an optical measurement system. In one example, an optical measurement system is disclosed that includes: (1) a pixel area of an optical sensor having multiple pixels that store an electrical charge corresponding to a received optical signal, (2) one or more reduced illumination regions that provide signal levels intrinsic to the optical sensor, and (3) one or more processors configured to adjust, during active operation of the system, digital representations of the electrical charges from the pixels of the pixel area using characterizations of the signal levels from the one or more reduced illumination regions.

Abstract: The disclosure provides processing of optical data with improvements in latency, repeatability, stability, signal detectability, and other benefits. The improved processing can be used to more accurately and consistently monitor and control semiconductor processes. In one example, a method of processing spectral data includes: (1) collecting a time-ordered sequence of optical emission spectroscopy data over one or more wavelengths, (2) extracting one or more attributes from the time-ordered sequence of optical emission spectroscopy data, (3) analyzing characteristics of the one or more attributes, (4) determining conditioning of the one or more attributes, (5) processing the one or more attributes according to a predetermined set of filters, the conditioning, and the characteristics, and (6) selecting a filter configuration for processing the spectral data based upon the processing of the one or more attributes.

Abstract: The present invention provides for making a comparison between a first video frame and a second video frame to determine the extent of a fear reaction in a test animal. Frame comparison logic is configured to quantify any change of a value associated with at least one pixel between the first video frame and the second video frame. A centroid calculator is configured to determine the position of a centroid of a video frame. Brainwaves of a test animal are also simultaneously measured and recorded. A processor correlates, as a matter of time, the recorded brainwaves with the change of status of the pixilated image information as a function of time.
