Claim 12:
13. The window system of claim 10, wherein the light source is a first light source operatively positioned on the first side, wherein the optical grating is a first optical grating operatively positioned on the first side, wherein the first light source is configured to emit light toward the first optical grating, and wherein the detector is a first detector operatively positioned to detect the wavelength of the light after it has interacted with the first optical grating, and further comprising:
a second optical grating operatively positioned on the second side, the second optical grating being used to determine a temperature of an external environment of the window on the second side;
a second light source operatively positioned on the second side, wherein the second light source is configured to emit light toward the second optical grating; and
a second detector operatively positioned to detect one or more wavelengths of the light after it has interacted with the second optical grating.
