Standard reflection-type supercontinuum spectrum imaging instrument

Abstract

The invention discloses a standard reflection-type supercontinuum spectrum imaging instrument, and the instrument consists of an embedded main controller, a terahertz scanning imaging subsystem, a multispectral imaging subsystem, a sample room, and a wireless local area network transceiver. The instrument provides a supercontinuum spectrum dodging laser source and a terahertz single-beam focusingscanning illumination method, and combines standard black and white boards for correction. Because the geometric shapes of feather and skin samples of rare animals cannot cover the whole image, the contour of the whole sample can be easily obtained through black base correction, and a standard reflectivity image of the sample can be obtained through white base correction. An active illumination imaging mode eliminates the impact from the ambient light, and the visible light, infrared and terahertz multi-band standard reflectivity images correlated with the tissue characteristics of the sampleare obtained. The instrument brings convenience to a custom import and export detection sanitary authority for the tracking, discrimination and protection of important biological resources.

Description

technical field [0001] The invention relates to a supercontinuum imager, in particular to a standard reflective supercontinuum imager using a supercontinuum homogeneous laser source and a single-beam scanning terahertz source, which is suitable for rare animal feathers, skins and other important biological The establishment and screening of resources belongs to the field of photoelectric imaging. Background technique [0002] In the field of import and export, most countries adopt strict control measures on the import and export of important biological resources. For example, the US Department of Agriculture's Animal and Plant Inspection Service stipulates that the entry and exit of genetic materials such as livestock, breeding eggs, animal semen, blood samples, embryos, and excreta are prohibited. In recent years, the number of animals and plants exported from China has increased year by year, but a comprehensive metadata database for identification of origin, physical pro...
