摘要： An IR sensor comprises a substrate, a rear reflector on the substrate, a supporting layer a PCM layer carried by the supporting layer, and first and second electrically conductive contacts carried by the substrate and coupled to opposing sides of the PCM layer. The IR sensor also includes a circuit coupled to the first and second electrically conductive contacts and configured to apply an electrical bias signal to the PCM layer to generate an electrical oscillation, and detect the frequency modulation (FM) of the oscillation signal based upon IR radiation received by the PCM layer.
