Laser array based detection device and pseudosciaena polyactis storage time detection method

Abstract

The invention discloses a laser array based detection device and a pseudosciaena polyactis storage time detection method. The method includes: firstly making the laser emitted by a laser array irradiate a sample, collecting the light reflected by the sample by an optical fiber probe and inputting the collected light into a spectrometer so as to obtain n detection signals corresponding to the wavelengths of n lasers; then adjusting the weight of each detection signal to obtain a satisfactory detection signal x(t), inputting the x(t) into a stochastic resonance system model prestored in a computer to make the stochastic resonance system model undergo stochastic resonance, then drawing an output signal noise ratio curve of the stochastic resonance system model by the computer, and conducting calculation by the computer to obtain a predicted pseudosciaena polyactis storage Time. With the characteristics of fast detection speed, high accuracy and good economical efficiency, the device and the method provided by the invention eliminates the interference information of useless band stray light, and the sample storage time is better differentiated.

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 small yellow croakers. Background technique [0002] Small yellow croaker belongs to the Sciaenidae family (Sciaenidae), also known as yellow croaker and stone head fish. The small 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 the small yellow croaker contains a large amount of selenium, it can better remove free radicals and beautify the skin. In addition, small yellow croaker is very rich in protein, and the meat is relatively delicate, which can be used as one of the ideal animal protein sources for human beings. Small yellow croaker is known as my country's four major economic fishes, especially in the development...
