Abstract
To detect a physical parameter, a resonator is connected to a body which changes in dimension when subjected to the parameter. Thus, when the body changes in dimension in response to the parameter, the resonance frequency of the resonator is modulated thereby. Such modulations are detected optically to detect and measure the parameter. In the preferred embodiment, the resonator transmits light and light is applied to the resonator so that the light supplied is transmitted through the resonator and so that the modulations of the resonance frequency also modulates the intensity of the light transmitted by the resonator. The modulations of the intensity of the light transmitted by the resonator is detected to detect the parameter.
