Heikki Saari (Inventor), Kai Ojala (Inventor)

Research output: PatentPatent


A spectral imaging device (500) comprises: - an optical modifier system (SYS1) to form axial light beams (LB2) from received light beams (LB1), the axial light beams (LB2) being parallel with an optical axis (AX1) of the imaging device (500), - a Fabry-Perot interferometer (FPI) to provide filtered axial light beams (LB3) by filtering light of the axial light beams (LB2), - an image sensor (SEN1), and - an array (ARR1) of lenses (LNS0,0, LNS0,1) to form a plurality of sub-images (S0,0, S0,1) on the image sensor (SEN1) by focusing light of the filtered light beams (LB3).
