| 摘要 |
The invention concerns a multimodal and highly compact human presence detector. The detector comprises, on a same silicon chip (10) made using CMOS technology, a first matrix 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 matrix 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 matrices by the visible light or the far-infrared radiation, the detector further comprising, on top of the silicon chip, an optical element (16) for focusing the far-infrared radiation on the first matrix, with an optical element for focusing the visible light on the second matrix. |
