| 摘要 |
A spectro-imager or spectrophotometer type optoelectronic camera comprising an optical system, a set of light-sensitive CCD elements (3) at the focus of said optical system, a clear protective window made, for example, of glass and placed in front of the sensitive side (4) of said set of light-sensitive elements (3), and a spectral scatterer for spectrally analysing the scene before said camera. Said sensitive side (4) of the set of light-sensitive elements (3), facing said protective window, is provided with a single- or multi-layer anti-reflective coating (9) with a thickness (e) that is continuously variable depending on the wavelength of the light picked up by said sensitive side in a direction parallel to the scattering axis of said scatterer (A). |
