Abstract:
1. A method for high-speed analysis of product samples comprising: transmitting an illumination light through a analyte multivariate optical element to form an analyte light, the multivariate optical element being positioned on a chopper wheel; illuminating a sample at an inspection point with the analyte light; transmitting the illumination light through a reference optical element to form a reference light different from the analyte light, the reference optical element being positioned on the chopper wheel and configured to correspond to the multivariate optical element; illuminating the sample with the reference light; providing a light sensitive detector, the detector producing an output signal based on received light; directing light from the sample toward the light sensitive detector, the light from the sample carrying information about the sample; and analyzing output signals produced by the detector, the analysis being based on a comparison of an output signal produced by the analyte light and an output signal produced by the reference light.
