“…Therefore, it is very important to stabilize the ray path geometries during the sensing operations. Using the piezoelectric-actuated mirror, it was possible to vary the optical ray path geometries inside the resonator cavity stably and with extreme precision [1,2]. After avoiding the lock-in effect [3][4][5], the focus on the conceptual design of the optical inertial sensor began to shift towards the practical solution of stabilizing the beam path [6][7][8][9] and, based on the optical ray path geometries without the structural consideration of the piezoelectric actuated mirror, the resonator design has been presented in order to avoiding the lock-in threshold as a function of path geometries [10].…”

In the operations of optical inertial sensors, geometric variations due to temperature and operation environments cause thermoelastic deformations of their components, which lead to changes in the area and perimeter of their resonator block. The fluctuations in the geometric scale factor are corrected by the piezoelectric actuator. This article presents the numerical formulation of the elastic behaviour of each piezoelectric actuator, and the numerical formulations are verified through comparisons with the results of a finite element simulation.

The principal operation of a ring laser gyroscope depends on the phase difference for the counter-propagating waves within a closed path. The reflection mirrors mounted on the resonator block form the traveling waves. Thus, the dimension accuracy of resonator block influences the traveling path of beam. In order to maintain the stable optical beam path in the ring resonator, the piezo-driven moveable mirror is adopted for the path length control under the thermal expansion or mechanical strain of resonator block. This paper presents the mathematical description of the elastic behavior of piezo-driven mirror. This description can be applied for the concept design of piezo-driven mirror. 요 약 링 레이저 자이로스콥의 주 동작은 폐경로 내의 상대 전파에 대한 위상 차에 의존한다. 공명 블록위에 설치 된 반사경들이 순항 파를 형성한다. 따라서, 공명 블록의 차원 정확도가 빔의 순항 경로에 영향을 미친다. 링의 공진 내에서 안정된 광학 빔 경로를 유지하기 위해서 피에조로 구동되는 이동거울이 공명 블록의 열팽창이나 기계적 변형 하에서 경로치 제어를 하고자 선택되었다. 이 논문에서는 피에조 구동 거울의 탄성거동에 대한 수학적 설명을 제시하 였다. 이 설명은 피에조 구동 거울의 개념 설계에도 적용될 수 있다.
