Abstract: Disclosed is a broad-spectrum imaging spectrometer based on reflection and transmission integrated structure, including a coaxial reflection outer cylinder and a coaxial transmission outer cylinder. A slit component is provided at an incident end of the coaxial reflection outer cylinder; a spherical mirror and a plane mirror are provided above the slit component; incident light passes through the plane mirror, reflects off the spherical mirror, and is further reflected by the plane mirror into the coaxial transmission outer cylinder; a grating prism module and a focusing inner cylinder are provided within the coaxial transmission outer cylinder along a transmission direction, and a cemented lens module is provided in the focusing inner cylinder; the cemented lens module is fixedly provided inside the focusing inner cylinder, the focus inner cylinder is placed within an adjustment chamber of the coaxial transmission outer cylinder.
Abstract: A hyperspectral camera based on a continuously variable film filter and a coating method thereof can solve interference between partial bands of the hyperspectral camera based on the continuously variable film filter. The hyperspectral camera includes: a camera body and a detector chip, wherein a continuously variable film is coated on the detector chip; a semi-transmission half-cut filter is provided in front of the continuously variable film, and a distance between the semi-transmission half-cut filter and the continuously variable film is 0 mm. According to the present invention, the semi-transparent half-cut filter and the detector chip are integrated without any gap therebetween. As a result, optical interference caused by incident light sequentially passing through the semi-transparent half-cut filter and the detector chip is greatly reduced, which can reduce distortion of spectral signals, and finally satisfy wide-band application requirements which can be truly realized based on such technology.
