Abstract: Systems and methods for measuring a target in a sample, the target being capable of generating an emitted light in response to an excitation light. In an example system, an excitation light source generates the excitation light along an excitation optical path. An attenuation filter arrangement selectively adds an attenuation filter to the excitation optical path. The attenuation filter attenuates the excitation light by a corresponding attenuation factor. The excitation light exits the attenuation filter arrangement along the excitation optical path to illuminate the sample. A light energy detector receives the emitted light generated in response to the excitation light, and outputs a measured signal level corresponding to an emitted light level. If the light energy detector indicates an overflow, signal measurement is repeated with attenuation filters of increasing attenuation factors until the measured signal level does not overflow.

Abstract: 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. 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.
