Investigation of Ground Cherry's Leafy Husk transparency to intense visible and laser light for quality control

樱桃和西红柿是同一科的植物。地面樱桃的一个显着特点是形成 指一个大的纸质外壳（多叶的信封），部分或全部包裹着果实。这种植物通常生长在 温暖的温度和亚热带地区;因此，在加拿大不太为人所知，因为我们的气候较冷。 国家然而，所有省份的少数农民种植并将其产品分销给当地市场。以来 由于这种植物在加拿大没有广泛种植，生产者在保存果实和增加产量方面遇到了困难。 收获的质量。在魁北克，只有一家樱桃粉生产商--费姆格兰杰公司， 位于Saint Jean sur Richelieu。我们的目标是通过评估地面是否 樱桃皮在开壳之前是完整的。该项目包括光学的调查， 传输特性的地面樱桃的外壳。为此，我们使用高强度光源， 可见光/近红外范围内，以评估叶信封的透射系数。这是一项研究， 应用物理学领域，由约翰·阿博特工程技术项目的学生完成 学院

Ground cherry is a plant in the same family as tomatoes. A notable feature of the ground cherry is the formation of a large papery husk (leafy envelope), which partly or fully encloses the fruit. This plant grows typically in warm temperatures and subtropical regions; thus, is less known in Canada due to the colder climate of our country. Yet, a few farmers in all the provinces plant and distribute their produce to the local market. Since the plant is not widely grown in Canada, producers have had difficulties in preserving the fruit and increasing the quality of their harvest. In Quebec, there exists only one producer of ground cherry - Ferme Granger Inc., located in Saint Jean sur Richelieu. We aim to increase the quality of the produce by evaluating if the ground cherry's skin is intact prior to the opening of the husk. The project consists of the investigation of the optical transmission properties of a ground cherry's husk. For that, we use high intensity light sources in the visible/near infrared range to evaluate the transmission coefficients of the leafy envelope. This is research in the field of Applied Physics which is done with students at Engineering Technologies Program at John Abbott College.
