1. A window, comprising:
a first side;
a second side substantially parallel to the first side;
a first optical grating operatively positioned on the first side and used to determine a temperature of an external environment of the first side;
a second optical grating operatively positioned on the second side and used to determine a temperature of an external environment of the second side;
a first light source operatively positioned on the first side and configured to emit light toward the first optical grating;
a first detector operatively positioned to detect one or more wavelengths of the light after it has interacted with the first optical grating;
a second light source operatively positioned on the second side and 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.
