The optoelectronic systems application for automatic qualification of fruits and vegetables

Summary form only given. One of the main tasks, that is being solved during the process of automatic sorting fruits and vegetables according to their quality is getting full information for the state of the quality of each product. This paper is focused on the results from the authors experience in using optoelectronic systems for the purposes of quality control and sorting fruits and vegetables according to their quality. A comparative analysis of the optoelectronic devices based on the light reflected and passed through the object has been made. The specific features of using synchronous and asynchronous principles for feeding the objects to the observation zone are shown. The conclusions concerning the influence between the characteristics of the optoelectronic devices and the accuracy of the sorting process are given
