Fiber-optic gyroscope temperature control structure and method for using same

Abstract

The invention provides a fiber-optic gyroscope temperature control structure and a method for using the same. The structure includes: first, second and third thermal insulation layers, first and second temperature control layers, a first heat insulation layer, a first temperature control layer, a second heat insulation layer, a second temperature control layer and a third heat insulation layer, all of which are sequentially arranged. The first heat insulation layer is arranged on the outer side of a fiber-optic gyroscope sensitive gauge outfit structure; the first heat insulation layer is usedfor carrying out heat insulation on the fiber-optic gyroscope sensitive gauge outfit structure; the first temperature control layer is used for maintaining the working temperature of the first temperature control layer within a first set temperature range; the second heat insulation layer is used for conducting heat insulation on the first temperature control layer, the second temperature controllayer is used for maintaining the working temperature of the second temperature control layer within a second set temperature range, and the third heat insulation layer is used for conducting heat insulation on the second temperature control layer to reduce the influence of external temperature disturbance on the temperature of the second temperature control layer. By applying the technical scheme of the invention, the technical problem that the temperature compensation method in the prior art is difficult to meet the precision requirement of the high-precision optical fiber gyroscope meter is solved.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscope temperature control, in particular to a fiber optic gyroscope temperature control structure and a method for using the same. Background technique [0002] With the improvement of fiber optic gyro technology, high precision, miniaturization, and low cost have become the development direction of fiber optic gyroscopes. However, due to the fundamental problems of fiber optic gyroscopes, fiber optic gyroscopes have strong temperature sensitivity, which can generally be improved by temperature compensation. The adaptability of the fiber optic gyroscope to the variable temperature environment improves the accuracy of the fiber optic gyroscope, but at the level of inertial fiber optic gyroscope accuracy, only relying on the temperature compensation method can no longer meet the accuracy requirements of the inertial class high-precision fiber optic gyroscope. The temperature of the sensitive...
