Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] see figure 1 As shown, the present invention is a kind of indexing mechanism suitable for the North Finder of the fiber optic gyroscope teaching experiment, and the indexing mechanism is composed of a bracket 1, a tray 2, a dial 4, a transparent indicator needle 15 and a spectrometer 3;

[0058] The dial 4 is a disc structure with engraved lines, and 360 engraved lines are engraved on the disc, and each engraved line represents 1° of rotation. A through hole is opened in the center of the dial 4 , and the through hole is used to sleeve the dial 4 on the D protrusion 183 of the rotating shaft 18 . The cooperation between the scale plate 4 and the transparent indicator needle 15 can observe the angle at which the rotating shaft 18 drives the tray 2 to rotate.

[0059] see Pic 4-1 As shown, the transparent indicator needle 15 is a transparent material...

Abstract

The present invention discloses a transposition mechanism of North Finder in the teaching experiment of optical fiber gyroscope. The transposition mechanism comprises a spectrometer (3), and is characterized by comprising a bracket (1), a tray (2), a dial (4), and a transparent indicating pointer (15); the bracket (1) consists of a right support plate (11), a left support plate (12), a bottom plate (13), a right bearing component (14), a left bearing component (19), an A bracket (16), a B bracket (17), a rotating shaft (18) and the transparent indicating pointer (15). The transposition mechanism has the following advantages: (1), the transposition mechanism has the functions of rotating and adjusting the horizontal shaft and the vertical shaft; (2) the transposition mechanism has a large size and high rigidity, and facilitates the installation of the optical fiber gyroscope with large size; (3) the whole body is made of aluminum alloy and other light materials, and thus being wholly light; (4) the level transposition rule and the observation window facilitate the operation and observation of students; and (6) the whole structure is wide, facilitates the operation, observation and manual adjustment, and has an attractive appearance.

Description

technical field [0001] The invention relates to an indexing mechanism suitable for a north-finder for an optical fiber gyroscope teaching experiment. Using the fiber optic gyroscope as an angular velocity sensor, a fiber optic gyroscope north finder suitable for teaching and demonstration is designed, which can realize the search for the geographic North Pole and the Earth's axis North Pole, as well as the measurement of latitude and the angular velocity of the earth's rotation. Background technique [0002] The law of mechanics tells us that the observer closed in a "black box" cannot know his motion in the uniform linear motion. But if this "black box" has acceleration, then it is possible to detect its linear acceleration or rotation, which is the basic principle of inertial guidance and navigation. Knowing the initial orientation and position of the moving body, the attitude and trajectory of the moving body are obtained by (mathematically) integrating the measured acce...
