A photothermal detector consisting of a relief grating on the surface of an elastomer was fabricated and characterized. The detector has a sensitivity of the order of microwatts per square millimeter and has rise and fall times of the order of tens of seconds. Numerical and analytical modeling account for the behavior of the detector.
