抜粋

High-quality fruits classified by ripeness of the fruits in a quantitative way are important for farm producers and customers. Therefore, many ripeness assessment methods, which are biochemical methods, physical methods, and optical methods, have been studied by researchers. The ripeness assessment techniques of fruits based on vibration tests have more potential because the techniques are based on nondestructive test. The ripeness of fruits is assessed by measuring natural frequencies of fruits in vibration tests, since firmness decline of fruits can be used to assess a ripeness of the fruits by past studies. In general, an impulse hammer and a shaker as contact-type excitation equipment are used in vibration tests for assessing ripeness of fruits. However, when target fruits are soft and small-sized as well as lightweight such as a grape, the implements with contact might not be used to assess the ripeness. In this paper, we measure natural frequencies of fruits in vibration tests using a shock wave generated by laser-induced plasma.
