Abstract

With the simultaneous development of jujube industry and intelligent agriculture, there is an increasing demand for collecting pre-evaluation of jujube quality using high technology. This paper proposes a non-contact multi-angle red jujube quality quantitative detection device based on light field modulation. This device realizes non-contact theoretical telemetry by superimposing multiple lenses in front of the spectrometer and uses the spatial light modulator SLM to change the size of the light field spot in order to change the detection range of the light field, and to explore the precision of red date quality detection under different light spots at multiple angles. After experimental verification, the moisture content of jujube tested by the detection device, the correlation coefficient of jujube correction set is 0.743, the correlation coefficient of prediction set is 0.694, and the average absolute error is 1.190%. The overall can make a preliminary judgment on the quality of jujube.
