Laser technology in agriculture, changing people grasp more accurately ripening season

Laser technology in materials processing, medical, communications, 3D printing, defense technology and applied research in the field has been maturing. But the application in agriculture is still relatively narrow, the latest news reports of laser technology can detect the crop is mature, which is a good news for agriculture, science and technology technology to promote the rapid development of agriculture.

In 1989, a movie called "Honey, I Shrunk the Kids", by Rick Mora made a nice play in the amateur scientist accidentally shrink ray machine of his own invention with a laser amplification apple. Now, scientists have found a better method of using a laser to cultivate apples: measure their maturity.

In an organism called speckle technique, the researchers used He - Ne laser irradiation golden apple surface, and then analyze how the light is reflected. The strength of the laser light is not great, just a few milliwatts than the average laser intensity index, but it will make Apple's smooth appearance accelerate some small flaws, causing irregular bounce laser and cause the surface of Apple's small-scale particles like appearance.

The group said that with the ripe fruit, the sample in the "hard-like particles" will gradually become smaller. They believe that this reduction is due to increased activity in the maturation of cells leads to the apples. To confirm whether or when these hard-like particles occurs in mature apples during the peak period, the team also monitored during the production of ethylene gas --- apple fruit maturation process until optimal peak and a known food value side effect. Once Apple missed the best period of development, the speed will slow down the ethylene gas produced by Apple's activity will be reduced, reflecting the size of those generated by the durum will increase.

Because the traditional method of detection is the outer layer of cut fruit or rely on subjective observation of the appearance, the researchers believe that the adoption of this technology could ultimately help farmers to accurately predict the best time to harvest crops of fruit and one can store up time.
