An image sensor for acquiring an image of an object comprises: an array of photo-sensitive areas (); and a mosaic filter () associated with the array dividing the array into sub-groups () of photo-sensitive areas () extending across at least two rows and two columns, wherein the mosaic filter () transmits unique light properties to the photo-sensitive areas () within the sub-group (); wherein the mosaic filter () comprises a sequence of unique filter portions associated with a set of photo-sensitive areas () along a row, wherein the set extends through more than one sub-group (); wherein sequences comprising the unique filter portions are associated with each row and wherein the sequences associated with adjacent rows comprise different orders of the unique filter portions, such that different light properties are transmitted to photo-sensitive areas () in the same column of adjacent rows.

Hyperspectral imager for snapshot and line-scan modes

The present disclosure relates to devices and methods for acquiring an image having two-dimensional spatial resolution and spectral resolution. An example method comprises: acquiring a frame using rows of photo-sensitive areas on a sensor surface detecting incident light from an object imaged by an optical system onto an image plane, wherein rows of photo-sensitive areas are arranged to receive different wavelengths; moving the sensor surface in a direction perpendicular to a longitudinal direction of the rows; repeating the acquiring and moving for acquiring a plurality of frames recording different spectral information for respective positions on the object; and combining information from the plurality of frames to form multiple channels of an image, wherein each channel is formed based on detected light in respective rows and represent a two-dimensional image of the object for a different wavelength.
