Abstract:
A polarization and color sensitive pixel device and a focal plane array made therefrom. Each incorporates a thick color/polarization filter stack and microlens array for visible (0.4-0.75 micron), near infrared (0.75-3 micron), mid infrared (3-8 micron) and long wave infrared (8-15 micron) imaging. A thick pixel filter has a thickness of between about one to 10× the operational wavelength, while a thick focal plane array filter is on the order of or larger than the size or up to 10× the pitch of the pixels in the focal plane array. The optical filters can be precisely fabricated on a wafer. A filter array can be mounted directly on top of an image sensor to create a polarization camera. Alternatively, the optical filters can be fabricated directly on the image sensor.
