Abstract
A method for forming a structure comprising multiple parallel surfaces having a precise separation is disclosed. Precise separation and parallelism of the surfaces is achieved through the use of an adhesive mixture that comprises a plurality of spacers having a dimension substantially equal to the desired separation.
Claims13
A method comprising:
- providing a first layer comprising a first surface;
- providing a second layer comprising a second surface, wherein the second surface is physically adapted to move in response to an environmental stimulus;
- securing the first layer and second layer together via an adhesive mixture, wherein the adhesive mixture comprises an adhesive and a plurality of spacers, and wherein each of the plurality of spacers is characterized by a dimension that is substantially equal to a first thickness, and further wherein the secured first surface and second surface collectively define an optically resonant cavity having an initial cavity length substantially equal to the first thickness;
- distributing light received by the optically resonant cavity into a reflected signal and a transmitted signal, wherein the light is characterized by a first wavelength, and wherein the ratio of light in the reflected signal and transmitted signal is based on the environmental stimulus;
- and
- producing a first electrical signal based on both (1) the intensity of the reflected signal and (2) the transmitted signal.

A method comprising:
- forming an optically resonant cavity having an initial cavity length, wherein the optically resonant cavity is formed by securing a first layer comprising a first surface to a second layer comprising a second surface that is physically adapted to move in response to a first environmental stimulus, wherein the first layer is secured to the second layer via an adhesive mixture comprising an adhesive and a plurality of spacers characterized by a dimension that is substantially equal to the initial cavity length;
- receiving light at the optically resonant cavity;
- distributing the light into a reflected signal and a transmitted signal based on the first environmental stimulus;
- producing a first electrical signal based on the intensity of the reflected signal;
- producing a second electrical signal based on the intensity of the transmitted signal;
- and
- producing a third electrical signal based on the first electrical signal and the second electrical signal.
