Embodiment Construction

[0042] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as figure 1 The illustrated embodiment is a detection device based on a laser array, including a spectrometer, a base plate 1 for placing the sample to be detected, and a support plate 2 above the base plate; the support plate is provided with a laser array for irradiating the sample to be detected 3 and the optical fiber probe 4 used to detect the reflected light after the laser light emitted by the laser array is reflected by the sample; the laser array includes 6 single-wavelength lasers bundled together, the optical fiber probe is electrically connected to the spectrometer, and the spectrometer is equipped with a computer for electrical connection. Connected signal output port.

[0044] The wavelengths of the individual single-wavelength lasers are 405nm, 980nm, 532nm, 808nm, 650nm, and 780nm, respectively.

[0045]The angle between t...

Abstract

The invention discloses a detection device based on a laser array and a large yellow croaker storage time detection method. Laser emitted by the laser array first irradiates a sample, light reflected by the sample is collected by an optical-fiber probe and then enters a spectrograph, the spectrograph obtains n detection signals corresponding to wavelengths of n lasers, a detection signal x(t) conforming to the requirement is obtained by adjusting the weight of each detection signal, the x(t) is inputted to a random resonance system model which is prestored in a computer, so that the random resonance system model has random resonance, and the predicted large yellow croaker storage time can be calculated through the computer. The detection device and the large yellow croaker storage time detection method have the characteristics that the detection speed is high, the accuracy is high, and the economic performance is good; interference information of useless waveband parasitic light is eliminated, and thus the storage time of the sample can be effectively distinguished.

Description

technical field [0001] The invention relates to the technical field of food quality detection, in particular to a detection device based on a laser array with high detection speed and high accuracy and a storage time detection method for large yellow croaker. Background technique [0002] Large yellow croaker belongs to the Sciaenidae family (Sciaenidae), also known as yellow croaker and stone head fish. Large yellow croaker is a dry-swimming fish clustered in warm-temperate coastal waters, and its main activity area is south of the central part of the South China Sea. Because it contains a large amount of selenium, it can better scavenge free radicals and beautify the skin. In addition, large yellow croaker is very rich in protein, and its meat is relatively delicate, which can be used as one of the ideal animal protein sources for human beings. Large yellow croaker is known as my country's four major economic fishes, especially in the development of marine fisheries in m...
