Title: Device for imaging scenes with very large ranges of intensity

Abstract

A device for imaging scenes with a very large range of intensity having a pair of polarizers, a primary lens, an attenuating mask, and an imaging device optically connected along an optical axis. Preferably, a secondary lens, positioned between the attenuating mask and the imaging device is used to focus light on the imaging device. The angle between the first polarization direction and the second polarization direction is adjustable.
