RESONANT OPTO-MECHANICAL ACCELEROMETER FOR USE IN NAVIGATION GRADE ENVIRONMENTS

摘要

An accelerometer (102) includes a controller (108), a light source (110) operatively coupled to the controller (108), and a bifurcated waveguide (112) coupled to the light source (110) and configured to receive light output by the light source (110). The bifurcated waveguide (112) includes a first waveguide portion (114) and a second waveguide portion (116). The accelerometer (102) also includes a first resonator (126) operatively coupled to the controller (108) and configured to receive light from the first waveguide portion (114), and a second resonator (128) operatively coupled to the controller (108) and configured to receive light from the second waveguide portion (116). The first resonator (126) includes a first proof mass (210), and the second resonator (128) includes a second proof mass (212).
