    • The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward an optical detector. Signals for the detector are compared with reference signals based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. Temperature within the analysis system is monitored and the output signals of the optical detectors are compensated or corrections are made within the analysis calculations to compensate or correct for the system temperature. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
    • 本主题涉及产品样品的高速分析方法。 光被引导到被分析的产品的一部分,从产品反射或透过产品朝向光学检测器。 基于通过参考元件的照明光的一部分,将检测器的信号与参考信号进行比较,以确定被分析产品的特性。 监测分析系统内的温度,并在分析计算中对光学检测器的输出信号进行补偿或校正,以补偿或校正系统温度。 被分析的产品可以是固定的,由检查点通过输送机或其他方式移动,或者可以容纳在容器内,该容器包括产品照明光通过的窗口部分。
