Abstract:
An optical system and method may relate to capturing extended dynamic range images. In an example embodiment, the optical system may include a lens element configured to receive incident light and a beam splitter optically coupled to the lens element. The beam splitter is configured to separate the incident light into at least a first portion having a first photon flux and a second portion having a second photon flux. The first photon flux is at least an order of magnitude greater than the second photon flux. A controller may be configured to cause a first image sensor to capture a first image of the first portion of the incident light according to first exposure parameters and cause a second image sensor to capture a second image of the second portion of the incident light according to second exposure parameters.
