1. An active illumination imaging system comprising: a light source that illuminates a scene imaged by the camera; and first and second cameras, each comprising an optical system having an optical axis and a photosensor having pixels on which the optical system images light, and a field of view (FOV) characterized by a view angle in a plane that contains the optical axis; wherein the optical axes of the first and a second cameras intersect at an intersection region common to their FOVs at an angle substantially equal to half a sum of their view angles to provide the imaging system with an enlarged FOV having an enlarged view angle in a plane defined by the intersecting optical axes that is substantially equal to a sum of the view angles of the cameras.
