Problems solved by technology

However, the gradient temperature field established by this structure in the water has a very small linear gradient range in the vertical direction, and the linear gradient temperature range is generally only 3-4cm. During the horizontal transmission process in the water tank, the light will soon enter the nonlinear gradient temperature region. (Nonlinear gradient refractive index region), making it very difficult to quantitatively study the transmission characteristics of light in the gradient refractive index medium in the tank
At the same time, only one gradient temperature field can be established in the same water tank at a time, which cannot satisfy the simultaneous observation, comparison, and measurement of the transmission of different curvatures of light in different gradient temperature fields in the same water tank

Description

technical field [0001] The invention belongs to the technical field of physical experiment teaching instruments, and in particular relates to optical experimental instruments. Background technique [0002] The bending transmission characteristics of light in inhomogeneous media not only reveal the physical essence of natural phenomena such as "mirages", but are also used in the research of long optical path transmission fields such as atmospheric optics, laser communication, optical fiber communication, and laser remote sensing, as well as gradient index optical elements. It has been widely used in the design and manufacture of devices and other modern technologies. However, people always have a certain degree of mystery about the phenomenon of bending transmission of light in inhomogeneous media. On the one hand, this is due to the concept of straight-line propagation of light formed by people since childhood, and on the other hand, it is difficult to observe the bending t...
