Portable optical detection probe for the internal quality of pachyderm fruits

Abstract

The invention discloses a portable interior quality optical detection probe for thick-skin type fruits. The portable interior quality optical detection probe comprises a spectral emitting device and a spectral receiving device which are coaxially mounted, wherein a heat dissipation lampshade is arranged in a ventilating cover; a halogen tungsten lamp is attached between the heat dissipation lampshade and an outer barrel; a plane mirror and the spectral receiving device are arranged in the outer barrel; the plane mirror is adhered to the top of an inner barrel cover and is aligned with the center of the halogen tungsten lamp; a mirror seat in an inner barrel is connected with the inner barrel cover; the elliptical plane mirror is adhered to a slope surface of the mirror seat; three inner fixing cylindrical holes in a cylinder on the outer side of the middle part of the inner barrel and three outer fixing cylindrical holes in a cylinder on the outer side of the middle part of the outer barrel are relatively formed, so that the inner barrel and the outer barrel are coaxially fixed; an optical fiber connection opening of the inner barrel and an optical fiber through hole of the outer barrel are butted and provided with optical fibers. The light source of the halogen tungsten lamp is integrated on the probe, so that the interior quality of the thick-skin type fruits can be particularly subjected to optical detection, and interior quality information of the fruits can be effectively acquired; a spectral basis can be supplied to lossless detection on the interior quality of the thick-skin type fruits.

Description

technical field [0001] The invention relates to a fruit quality detection device, in particular to a portable optical detection probe for the internal quality of thick-skinned fruits. Background technique [0002] With the improvement of living standards, consumers have higher and higher requirements for the quality of fresh fruits, not only requiring the appearance of fruits to be beautiful, but also the requirements for internal quality such as sugar content and acidity. The maturity of melon and fruit when picking is an important factor to determine its internal quality. Harvested too early, the organs of melon and fruit products have not yet reached the mature standard, the weight of a single fruit is small, the yield is low, and the quality is poor. Although the color, aroma, and taste of the product itself cannot be fully expressed, the storability is also poor; harvested too late , the fruit has matured and is close to the senescence stage, so it must not be resistan...

Problems solved by technology

[0004] In order to overcome the problem that the light intensity of the diffuse reflection ring light source probe in the background is weak or the coverage wavelength is small, resulting in the inability to detect thick-skinned fruits, the purpose of the present invention is to provide a portable optical detection probe for the internal quality of thick-skinned fruits, which can be used Detection of the quality of thick-skinned fruits in the field and other occasions
