Problems solved by technology

At present, there are experimental demonstration devices about the thermo-optic effect of transparent liquids, such as the Chinese invention patent application (application number 201710543136.0) "Experimental device and experimental method for light transmission characteristics in heterogeneous media", which discloses a gradient temperature field in water, The technical scheme of visually demonstrating the thermo-optic effect of water by using the bending propagation phenomenon of the laser beam horizontally through the water, and the research on the thermo-optic effect of solid media is basically carried out for solid thin film materials, and rarely involves bulk solids Research on the thermo-optic effect of medium, but to demonstrate the thermo-optic effect of solid media intuitively, a stable gradient temperature must be established in a large-scale transparent bulk solid medium, and there is no related report at present. Experiments demonstrating the thermo-optic effect of transparent solid media The device is currently in a blank state, so it is urgent to develop an experimental device that can directly demonstrate the thermo-optic effect of transparent block solid media
