Abstract :
A new optical method for detection of spines during the laser de-thorning process is presented. The spines detection is performed by on-line measurement of reflectance using a low power 532 nm, CW Nd:YAG laser. It´s demonstrated that the method avoids enhancing the throughput and efficiency of laser dethorning of opuntia.
