Claim 0:
1. A system, comprising:
a structure defining an opening;
a window operatively positioned within the opening, the window being movable to selectively open and close the opening, the window including an optical grating operatively positioned near a closing edge of the window;
a light source configured to emit light toward the optical grating;
a detector operatively positioned to acquire spectroscopic data of the light emitted from the light source after the light has interacted with the optical grating; and
a processor operatively connected to the detector, wherein the processor is configured to:
determine a temperature based on the spectroscopic data;
determine, based on the temperature, whether an object is located in the opening; and
responsive to determining that an object is located in the opening, control a movement of window.
