Description

technical field

[0001] The invention relates to a fiber grating sensing experiment instrument, which belongs to the technical field of teaching experiment instruments for physics, optics, optoelectronics, precision instruments and detection technology. Background technique

[0002] At present, the current, vibration, displacement, and tilt angle teaching experiments used in the prior art mostly use certain special instruments and equipment. If you want to carry out teaching experiments or demonstrations on the above-mentioned parameters, you need to purchase multiple different instruments and equipment. Not only increased the expenditure, but also increased the required experimental space. Fiber Bragg Grating Sensing Experimental Instrument is rarely used in teaching experiments. At present, Tianjin Gangdong Science and Technology Development Co., Ltd. has developed a SGQ-1 Fiber Bragg Grating Sensing Experimental Instrument. The instrument consists of a testing unit and a s...
