IEEE Geoscience and remote sensing (GRSS) - Gujarat, IEEE MTT/AP- Gujarat, Indian Society of Geomatics (ISG) - Ahmedabad Chapter and CEPT University organized an invited lecture on the topic “Remote Sensing of the Physical Qualities of Fruits” delivered by Dr. Monai Krairiksh affiliated with King Mongkut’s Institute of Technology, Ladkrabang, Bangkok 10520, Thailand. The main purpose to organize this event in India was because the climatic condition of Thailand and India matches and both are having high fruit production. The main objective was to detect the ripen fruits so as to avoid it from being rotted. He included both the techniques of post-harvest and pre-harvest. This technique will be beneficial for fruit merchants and they will be saved from heavy losses. His main concentration was on a fruit named Durian found in Malaysia and Thailand which is having many ethical as well as economical values to them. Measuring the dielectric constant of a fruit sample using radiation in microwave region can be helpful to determine the current state of a fruit and it can be harvested at an appropriate time. The main advantage of this technique is that by simulating the spectral response of a fruit, its quality parameters like ripeness, sugar content, thickness of the skin etc can be found out without destroying the fruit. By this method a large number of fruits in the orchard can be individually harvested at the time when they in a state most suitable for export. Other fruits included were Mango, Watermelon, and Orange. Researchers are being made to develop a hand held device which could be user friendly.

55 students from CEPT, 2 RA’s of CEPT and 1 student from LDRP-ITR, Gandhinagar were part of event. Dignitaries from Space Applications Centre – ISRO, PRL, PDPU, and other organizations were present.
