Abstract
A multimodal imaging system comprises a light source, an image sensor comprising a plurality of pixels, and an optical filter comprising a first filter element and a second filter element. The light source emits partially coherent polarized light, and the first filter element and second filter element are arranged as an array parallel to the image sensor. The first filter element is configured for attenuated transmission of a first light spectrum, which comprises polarized light emitted by the light source, and the second filter element is configured for transmission of a second light spectrum. The image sensor is configured to simultaneously capture light impinging on the image sensor from both the first filter element and the second filter element. Each filter element of the optical filter is configured for transmission of light to a subset of the imager pixels.
