    摘要: An example method and hyperspectral imaging (HSI) system for imaging a scene are provided. The method is for imaging the scene with the HSI system including a sensor with a plurality of sensor pixels and a plurality of spectral filters, each of the spectral filters being associated with one of the sensor pixels. The method comprises obtaining a higher-resolution spatial image by illuminating the scene with a first set of wavelengths, wherein each spectral filter passes the first set of wavelengths to the sensor pixel it is associated with. The method further comprises obtaining a lower-resolution hyperspectral image by illuminating the scene with a second set of wavelengths, wherein each spectral filter passes only a subset of the second set of wavelengths to the sensor pixel it is associated with.

    摘要: Embodiments described herein relate to lens-free imaging. One example embodiment may include a lens-free imaging device for imaging a moving sample. The lens-free imaging device may include a radiation source configured to emit a set of at least two different wavelengths towards the moving sample. The lens-free imaging device is configured to image samples for which a spectral response does not substantially vary for a set of at least two different wavelengths. The lens-free imaging device may also include a line scanner configured to obtain a line scan per wavelength emitted by the radiation source and reflected by, scattered by, or transmitted through the moving sample. The line scanner is configured to regularly obtain a line scan per wavelength. Either the radiation source or the line scanner is configured to isolate data of the at least two different wavelengths.

    摘要: A spectrometer module comprising a plurality of separate electronic circuit modules is disclosed. Each separate electronic module comprises an integrated sensor circuit including a light sensitive area occupying part of an area of the integrated sensor circuit, the integrated sensor circuit being arranged to detect incident light. In one aspect, the plurality of separate electronic circuit modules includes a group of adjacent electronic circuit modules. The light sensitive areas of the electronic circuit modules in the group are so arranged on the respective integrated sensor circuits that the group of adjacent electronic circuit modules is mounted so that the light sensitive areas thereof are arranged in vicinity to each other. The spectrometer module includes an optical module, which is common to said plurality of separate electronic circuit modules and arranged to direct incident light towards the light sensitive areas of each of said electronic circuit modules.
