    摘要： A water quality detection system including a light source, a spectrometer, and a data processor is disclosed, and relates to the technical field of detection systems. The light source emits excitation light pulse trains of different wavelengths to a to-be-detected water sample contained in a sample cell, where the excitation light pulse trains of different wavelengths may be emitted in a time-division manner, to excite the to-be-detected water sample, thereby generating fluorescence separately corresponding to the excitation light pulse trains of different wavelengths. The spectrometer receives the fluorescence and output a fluorescence spectrum based on the fluorescence. The data processor obtains, based on the fluorescence spectrum output by the spectrometer, a three-dimensional fluorescence spectrum including an excitation wavelength, a fluorescence wavelength, and a fluorescence intensity, identifies the to-be-detected water sample and obtains a parameter of the to-be-detected water sample based on the three-dimensional fluorescence spectrum.

    摘要： An optical measurement probe for capturing a spectral response through an intervening material emitting unwanted background radiation includes: a first lens configured to receive light and collimate the light into a collimated excitation beam defining a first aperture; an objective element for focusing the collimated excitation beam to a point or region in a sample through the intervening material, wherein the objective element also receives light scattered by the sample and the intervening material and collimates the scattered light into a collimated collection beam defining a second aperture; and a blocking element within the collimated collection beam for removing the light scattered by the intervening material from the collimated collection beam received from the sample, wherein the second aperture defined by the collimated collection beam is at least two times greater than the first aperture defined by the collimated excitation beam.

    摘要： This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.
