Problems solved by technology

[0003] However, at present, the laser mode adjustment and Sagnac effect in the undergraduate teaching of colleges and universities are mainly based on principle explanation and formula derivation, and there are few corresponding demonstration experiments.
On the one hand, it is because there are many complete sets of equipment in the laser gyroscope demonstration system (helium-neon laser tube, laser mirror, single-mode calibrator, photodetector, frequency counter, oscilloscope, etc.) and the cost is high; The operation requirements of the operator are high, and it is difficult to control the process to obtain ideal experimental results, so it is not suitable for setting up experimental courses with limited time.

Embodiment 1

[0048] The system of the present invention can explore the relationship between the cavity length of the straight cavity mode and the spacing of the longitudinal mode. This experiment uses a laser module, a cavity tuning module, and a control and display device.

[0049] Specific steps are as follows:

[0050] Such as Figure 4 As shown, the collimating laser 3, the helium-neon laser tube 2, the diaphragm 4, the first reflector 1-1 and the second reflector 1-2 are installed on the base 9 with the adjustment bracket (see image 3 ), the base is punched with precise matrix installation holes, where the first reflector 1-1 is placed on the far left, and the helium-neon laser tube 2 with the Brewster window is installed on the right. The first reflection mirror 1-1 and the second reflection mirror 1-2 are total reflection mirrors, preferably, the first reflection mirror 1-1 is a concave mirror, and the second reflection mirror 1-2 is a plane mirror.

Embodiment 2

[0058] The system of the present invention can also be used to demonstrate the tuning and collimation process of the ring resonant cavity, and the system needs to use a laser module and a cavity tuning module.

[0059] Such as figure 2 Shown:

[0060] (1) Set the collimation reference laser line

[0061] Fix the collimated laser 3 on the adjustment platform, turn it on, emit the laser beam, adjust the pitch angle of the indicator laser 3, make the collimated laser beam parallel to the precision optical flat plate 10, and be in a horizontal state. This collimated laser is used as the collimated reference laser line .

[0062] (2) Adjust the He-Ne laser tube 2 with the Brewster window to be horizontal

[0063] (3) as shown in embodiment 1, make the helium-neon laser tube 2 of band Brewster window go out light

[0064] At this time, it can be determined that the He-Ne laser tube 2 with the Brewster window, the center of the aperture 4 and the light of the collimator 3 are in...

Embodiment 3

[0070] The system of the present invention can also be used to demonstrate and explore the relationship between the cavity length of the annular cavity mode and the spacing of the longitudinal mode.

[0071] Such as figure 2 As shown, the system uses a laser module, a cavity tuning module, a light combination system 5 , an information collection module 6 and a control and display device 7 .

[0072] Adjust each equipment according to embodiment 2. Connected to the combined light system 5, the resonant light generates interference light, and the interference light signal of the system is collected through the information collection module.

[0073] Such as Image 6 with Figure 7 As shown, the software in the control and display device 7 can directly store data, plot and analyze data.

[0074] Change the cavity length of the annular cavity mode, observe the change of the interval of the longitudinal mode on the computer software page, and explore the relationship between t...

Description

technical field [0001] The present invention relates to the technical field of laser gyroscopes, and more specifically, to a teaching and demonstration system for laser gyroscopes. Background technique [0002] Laser gyro is a sensor used to measure the angular rate of moving objects, and it is one of the commonly used sensor types in modern inertial navigation technology. The laser mode adjustment and Sagnac effect demonstration involved in the basic field of laser gyroscope are important basic concepts in the application of laser gyroscope technology. In the production and application of many gyroscopes, it is necessary to learn the laser mode and Sagnac effect first, and the theory involved is very Strong, but the conclusions mentioned in theoretical classes in university courses are generally obtained through complex mathematical derivations, the process is very abstract, and students learn obscure and boring. In order to strengthen students' understanding and applicati...
