An analysis is presented to estimate the perturbation of morphology dependent optical resonances (MDRs) of spherical dielectric cavities due to acceleration and angular velocity. In the model, the optical cavity is attached to a rigid base that is accelerating. Hertz contact theory is used to describe the contact surface between the base and the sphere, and the Navier equation is solved to obtain an expressio n for MDR shift dependence on the base acceleration. The analysis is also extended to a rotating resonator. E xperiment s are also carried out using a polydimethylsiloxane sphere as the optical cavity. The predictions using the analysis agree well with the e xperimental results.
