Development of optical sensor in measurement of apple quality

A non-contact Near Infrared Spectroscopy (NIRS) techonology is used for measurement of apple quality by employing a diffuse reflection of fiber optic probe, whereby this technology has been widely used as an analysis method of agriculture, food etc due to low cost, minimal sample size and faster.
