Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0029] Optical interference technology refers to a method in which a beam of light waves reflected, refracted or diffracted by an object is superimposed with another beam of light waves reflected by the surface of a reference mirror to produce interference fringes. Laser interferometry is used in precision measurement in many fields, such as optical fiber sensing, microscopic profile restoration, surface profile measurement lamps, etc.
[0030] When laser interferometry is used for measurement, interference fringes are the carrier of measurement information. By analyzing the interfere...

The invention relates to a laser-interference color sorting device. The laser-interference color sorting device comprises a feeding mechanism, a color sorter body and a distributing hopper which are connected in sequence and further comprises a control system; the color sorter body comprises a shell and further comprises an optical system and a spray valve which are arranged in the shell; and theoptical system comprises an optical source, an optical path module and an image sensor, the spray valve, the feeding mechanism, the image sensor and the optical source are all connected with the control system, and a laser source is adopted as the optical source. Compared with the prior art, lasers have good monochromaticity, directionality and high brightness, an interference image is prone to being generated, stability is higher, the laser source has certain penetrability, thus internal defects of materials can be detected, the laser-interference color sorting device does not need to be awayfrom light, and the influence of environment light on the laser-interference color sorting device is small.
Description
technical field [0001] The invention relates to a color sorter, in particular to a laser interference color sorter. Background technique [0002] The color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. At present, the color sorter is used in the fields of bulk materials or packaging industrial products, food quality testing and grading. [0003] In order to adapt to the current application of color sorters in some industries, higher requirements are put forward for the sorting accuracy of color sorters. Chinese patent CN111167747A discloses a new type of color sorter based on white light Michelson interference, including sequentially connected feeding mechanism, color sorter body and hopper, and a control system. The color sorter body includes a casing, and a first optical system and a spray valve arr...
