  • Abstract
    A novel polarisation-analysing CMOS photosensor is proposed, and its application demonstrated. A wire grid structure configured with a metal wiring layer on a photosensor pixel is used as an embedded polariser. The polarisation-dependent sensitivity of the photosensor is demonstrated even in a wavelength region that is smaller than the grid pitch. The polarimetric measurement of a sucrose solution is also demonstrated successfully.
