Abstract
Described is a tilt meter for monitoring angle shift in an incident signal. The tilt meter includes a resonator for receiving an incident signal from a signal transmitter and outputting a resonated signal. An incident angle exists between a plane normal to the resonator and the incident signal. A sensor is included for sensing the resonated signal. A processor is connected with the sensor and is configured to compare intensities of the incident signal and the resonated signal. Based upon the comparison, the processor determines if and by how much the incident angle has changed.
Claims14
A tilt meter for monitoring angle shift in an incident signal, comprising:
- a resonator for transmitting or reflecting an incident signal that is introduced to the resonator as a plane wave, such that an incident angle exists between the plane wave and a plane normal to the resonator, the resonator further being capable of transmitting or reflecting the incident signal as a resonated signal;
- a sensor for sensing the resonated signal;
- and
- a processor connected with the sensor and configured to compare intensities of the incident signal and the resonated signal, and based upon the comparison, determine by how much the incident angle has changed.
A method for monitoring angle shift in an incident signal, comprising acts of:
- introducing an incident signal to a resonator as a plane wave such that an incident angle exists between the plane wave and a plane normal to the resonator, wherein the incident signal has an incident signal intensity and the incident signal is introduced to the resonator such that upon contact with the resonator, the incident signal becomes a resonated signal with a resonated signal intensity;
- receiving the resonated signal;
- measuring the difference between the incident signal intensity and the resonated signal intensity;
- and
- calculating a change in the incident angle based on the difference between the intensities.
A computer program product for monitoring angle shift in an incident signal, the computer program product comprising computer-readable instruction means encoded on a computer-readable medium that are executable by a computer for causing the computer to:
- receive information corresponding to an incident signal intensity, the incident signal intensity being a signal intensity of an incident signal that is introduced to a resonator as a plane wave such that an incident angle exists between the plane wave and a plane normal to the resonator;
- receive information corresponding to a resonated signal intensity, the resonated signal intensity being a signal intensity of resonated signal, where the incident signal is introduced to the resonator such that upon contact with the resonator, the incident signal becomes the resonated signal;
- measure the difference between the incident signal intensity and the resonated signal intensity;
- and
- calculate a change in the incident angle based on the difference between the intensities.
