Abstract
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.
