Abstract
An apparatus and method for estimating a parameter of interest using values of a beam property from two or more electromagnetic beams that both pass through at least part of an optical displacement device. The apparatus may include a Fabry-Perot interferometer, a collimated light source, and a detection array. At least one mirror of the interferometer may be operably coupled to an element receiving an external stimulus, such as pressure, force, and/or acceleration. The method includes using the apparatus.
Claims18
An apparatus for estimating a parameter of interest, comprising:
- an optical displacement device configured to receive a first electromagnetic beam with a first angle of incidence value and a second electromagnetic beam with a second angle of incidence value;
- and
- a detector array configured to receive a part of the first electromagnetic beam and a part of the second electromagnetic beam that both pass through at least part of the optical displacement device.
A method for estimating a parameter of interest, comprising:
- estimating the parameter of interest using a detector array configured to receive a part of a first electromagnetic beam with a first angle of incidence value and a part of a second electromagnetic beam with a second angle of incidence value that both pass through at least part of an optical displacement device.
