A Standard Reflective Supercontinuum Imaging Method

Abstract

The invention discloses a standard reflection type continuous spectrum imaging method. The method is realized based on standard reflection type continuous spectrum imager and comprises the following five steps: laser multispectral imaging calibration, terahertz scanning imaging calibration, laser multispectral imaging, terahertz scanning imaging and image post-processing. The method has the beneficial effects that a super-continuum spectrum homogeneous laser source and a terahertz single-beam focusing scanning illumination method are provided and are combined with standard black-white board correction, the whole image cannot be covered with geometrical shapes of samples such as rare animal feather, pelt and the like, the outline of the whole sample can be easily acquired through black bottom correction, and a standard reflection rate image of the sample can be acquired through white bottom correction; and by utilizing an active illumination imaging mode, the influence of environmentallight is eliminated, and a visual light, infrared ray and terahertz multi-pass band standard reflection image which is only relevant with texture characteristics of the sample is obtained, so that thesource tracing, identification and protection can be conveniently realized by custom import-export detection and quarantine departments.

Description

technical field [0001] The invention relates to a supercontinuum imaging method, in particular to a standard reflective supercontinuum imaging method 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 orig...
