ABSTRACT:
Certain embodiments of the invention provide a light sensor comprising at least one interferometric element that absorbs light in at least one wavelength. The interferometric element comprises a first surface and a second surface substantially parallel to the first surface. The second surface is spaced a gap distance from the first surface in a direction substantially perpendicular to the first surface. The light wavelength absorbed is dependent on the gap distance. The interferometric element further comprises a temperature sensor. The temperature sensor is responsive to changes in temperature of at least a portion of the interferometric element due to absorption of light by the interferometric element.
