RAMAN LASERS FOR FRUIT QUALITY CONTROL Raman spectroscopy is a new method to control the quality of fruits . It allows a non-destructive investigation of the freshness of fruits and to sort out those fruits that are no longer attractive to consumers . Another application is the non-destructive , rapid and accurate detection of pesticide residues on the surface of fruits . FLC offers a great variety of Raman Lasers for Raman spectroscopy in the visible and near infrared wavelength range .
LINE LASER MODULES FOR ALIGNMENT OF FRUITS Sorting and quality inspection of fruits is still a time-consuming task because of the low level of automation . Natural products exhibit a greater variance compared to manufactured products regarding quality and dimensions , which complicates their automated processing . By means of a red line laser like a laser from the ML2040-Series or the HAML-F in combination with a color CMOS camera and a specially trained Convolutional Neural Network it is possible to determine the orientation of fruits . The accuracy of the orientation prediction is approximately 5 degrees , which presents very promising results for the automation of fruit packing systems .
