    Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, a mosaic of filters for passing different bands of the optical spectrum, and a sensor array 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. Further, 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.

    Abstract: A variable wavelength optical filter module according to the present invention includes a package, a variable wavelength optical filter, and a detector. The package includes a reflection part (reflecting faces) in the inside of the package. The variable wavelength optical filter is disposed in the inside of the package and includes a first reflecting plate and a second reflecting plate facing each other, with a clearance between the first reflecting plate and the second reflecting plate being variable. The detector is disposed in the inside of the package and detects a ray of light having passed through the variable wavelength optical filter. Then, the variable wavelength optical filter and the detector are disposed on the opposite side to the reflection part (reflecting faces). The ray of the light incident into the inside of the package via the variable wavelength optical filter enters the detector via the reflection part (reflecting faces).

    Abstract: A spectrometer comprises a substrate and a waveguide on the substrate, the waveguide including an elongate part and a tapered input for guiding electromagnetic radiation to the elongate part. The tapered input includes an input end for receiving the electromagnetic radiation and an output end coupled to the elongate part, the input end being wider than the output end. The spectrometer may further comprise a plurality of resonators coupled to the elongate part of the waveguide.
