Description

Technical Field

[0001] The invention relates to a popular science device for demonstrating active infrared imaging technology, which is specifically used for displaying optical technology in a science and technology museum and belongs to the field of optical popular science education. Background Art

[0002] The principle of active infrared imaging technology is mainly to emit an infrared beam to the target, which will reflect back the infrared image after irradiating the target and achieve the imaging effect by converting it into a visible light image.

[0003] When active infrared imaging technology is used for underwater imaging, infrared light can penetrate water to a certain depth. The infrared light source emits infrared light with a wavelength range of 0.78 to 1.1 microns that is invisible to the human eye to illuminate the observed object, and uses the reflected infrared light to form an image.

[0004] Active infrared imaging technology has certain advantages in underwater applications. First, actively emitting infrared light can overcome the problem of insufficient light in the underwater environment to a certain extent and provide additional light sources for underwater imaging. Second, active infrared imaging technology can adapt to different underwater environments and imaging requirements by adjusting the power and angle of the infrared transmitter.

[0005] Active infrared imaging technology is widely used in underwater imaging fields such as marine biological research, underwater engineering inspection, underwater security and search and rescue, and underwater archaeology, and has obvious technical advantages. At present, the existing popular science exhibits in the science and technology museum are mainly concentrated in the fields of passive infrared imaging and thermal imaging, and there are no exhibits showing active infrared imaging in underwater imaging. Although the audience can understand the basic knowledge of infrared imaging, they lack ways to understand active infrared imaging technology and its application in underwater imaging. Therefore, how to vividly and intuitively display the technology of infrared technology in underwater imaging has become an urgent problem to be solved in the popular science exhibition of the science and technology museum. Summary of the invention
