<p>A spectral camera for producing a spectral output has an objective lens (10) for producing an image, a mosaic of filters (30) for passing different bands of the optical spectrum, and a sensor array (40) arranged to detect pixels of the image at the different bands passed by the filters, wherein for each of the pixels, the sensor array has a cluster of sensor elements for detecting the different bands, and the mosaic has a corresponding cluster of filters of different bands, integrated on the sensor element so that the image can be detected simultaneously at the different bands. The filters are first order Fabry-Perot filters, which can give any desired passband to give high spectral definition. Cross talk can be reduced since there is no longer a parasitic cavity.</p> |
