Abstract

The invention provides a multi-spectral camera device. The multi-spectral camera device comprises a laminated hybrid semiconductor device, wherein the laminated hybrid semiconductor device is used for performing channel separation on different wave bands in a three-dimensional space and comprises a first photoelectric diode and a second photoelectric diode, the first photoelectric diode is used for photoelectrically converting near-infrared light, the first photoelectric diode forms an infrared image detection array and comprises a substrate and an electron and/or hole depletion layer, the electron and/or hole depletion layer is formed in the substrate, the second photoelectric diode is arranged on the first photoelectric diode and is used for photoelectrically converting visible light, and the second photoelectric diode forms a visible light image detection array. With the multi-spectral camera device provided by the invention, the interference between the different photoelectric diodes is reduced or prevented, the integral performance is improved.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a multispectral camera device. Background technique [0002] The structures and tissues inside the human body cannot be directly seen by the human eye. It is difficult to accurately find and locate the subcutaneous internal structure and tissue only relying on the external contour of the human body and the knowledge of human anatomy. [0003] Human blood vessels are hidden under the epidermis, often blocked by subcutaneous fat or even bones, and the image signal is extremely weak in a visible light environment, or even completely invisible to the human eye. Although before puncture, doctors often ask patients to clench their fists or pat the skin at the puncture site to make blood vessels more visible, but depending on factors such as the age of the patient and the thickness of subcutaneous fat, the visibility of subcutaneous blood vessels is still not ideal. Accordin...
