Abstract
An apparatus and a method of determining a state of an actuator in an airplane. The apparatus includes a mirror coupled to the actuator, wherein a location of the mirror is dependent on the state of the actuator, a shaft for moving the mirror upon a change in the state of the actuator, and a processor. Incident light is reflected off of the mirror to create a reflected light. The processor receives the reflected light from the mirror, detects a change in a parameter of the reflected light generated by moving of the mirror, and determines the state of the actuator based on the change in the parameter.
