Multispectral light resource and multispectral imaging system

Abstract

The invention provides a multispectral light source and a multispectral imaging system, and relates to the technical field of photology. The multispectral light source comprises a lamp head and a filter converter; the lamp head is connected with the filter converter, and the light outlet of the lamp head is aligned with the light outlet of the filter converter; the lamp head comprises a lamp box and a flash bulb arranged in the lamp box, and the flash bulb is used for emitting full spectrum light; and the filter converter comprises a plurality of rotatable filters, and the transmission spectrum of different filters is different. According to the multispectral light source, the flash bulb which can emit full spectrum light is adopted, and through the filtering effect of the different filters on the filter converter, radiation light of different spectral range can be output. Compared with the prior art, according to the provided multispectral light source and the multispectral imaging system, the portability, controllability, working flexibility and working efficiency of the radiation light source are improved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a multispectral light source and a multispectral imaging system. Background technique [0002] The multi-spectral photography image analysis method is a non-destructive analysis method that displays and analyzes the material information of the surface layer of the material through the image of the reflection, absorption or fluorescence radiation characteristics of the material in different bands of the spectrum. Based on the imaging results of the multi-spectral imaging system, this method can extract painting information from the surface of ancient murals and painted relics, and make a preliminary judgment on the distribution category and state of the surface distribution materials. In the whole multispectral analysis, the role of the radiation source of the multispectral imaging system is very important. Under different bands of radiation sources, low-pass filters or band-pass...

Problems solved by technology

[0003] At present, the radiation light source in the multispectral imaging system usually includes multiple light sources, such as using a photographic light to take visible light images and infrared images, and using a 356nm black light lamp to take ultraviolet reflection images and ultraviolet fluorescence images. The large size of the radiation light source leads to portability. poor

In actual operation, it is necessary to continuously switch the light source to complete the shooting of visible light images, infrared images and ultraviolet images. The user's operation is more difficult, resulting in poor work flexibility and low work efficiency.
