摘要： A multimodal and highly compact human presence detector that includes, on a same silicon chip made using CMOS technology, a first array of pixels, made sensitive to far-infrared radiation by depositing a pyroelectric layer, converting the received far-infrared radiation into electrical charges, juxtaposed with at least one second array of pixels sensitive to visible light, converting the received visible light into electrical charges, and a circuit for reading the charges generated in each of the arrays by the visible light or the far-infrared radiation, the detector further including, on top of the silicon chip, an optical element for focusing the far-infrared radiation on the first array, and an optical element for focusing the visible light on the second array.
