Abstract
A thermal detector with a suspended absorbent membrane, which has at least two absorbers. The second absorber is designed to absorb the electromagnetic radiation in a spectral sub-band of a predefined spectral band, centered on a wavelength λ. Moreover, it is spaced from a reflector by a value equal to λ/4nso as to form therewith a quarter-wave cavity for the wavelength λ, the spectral sub-band being centered on the wavelength λwhich is equal to λ/2 within plus or minus 2 μm. Furthermore, the first and second absorbers have total surface areas such that a surface area ratio is between 0.5 and 3.
