摘要
A device and a method for high-speed linear polarization imaging of a scene are disclosed. The device comprises a polarization modulator for modulating the polarization of light emitted from the scene in order to obtain at least three linear polarization states of the light. The polarization modulator comprises a polarizer, a first polarization rotation block comprising a fixed quarter-wave plate and a first liquid crystal operating as a quarter-wave plate, and a second polarization rotation block comprising a second liquid crystal operating as a half-wave plate. Each of the first and second liquid crystals are switchable between two states, thereby providing the at least three polarization states to the polarization modulator. The device further comprises a sensor adapted to capture image frames of the light from the scene at each polarization state of the polarization modulator.
