| 摘要 |
The present invention relates to a bispectral detection device, particularly of an infrared radiation and a visible radiation, including a monolithic substrate; an array of bolometric micro-bridges sensitive to infrared radiation, the bolometric micro-bridges being suspended over a first face of the substrate by means of support and connection arms; and an array of photoelectric elements fowled in the substrate, and sensitive to visible radiation, the bolometric micro-bridges and the photoelectric elements being stacked. According to the invention, the substrate portion between the photoelectric element array and a second face of the substrate, opposite to the first face thereof, is thinned so that the photoelectric elements are capable of detecting a visible radiation incident on the second face.
