Abstract:
This disclosure is directed to systems and methods for acquiring IR light and visible light images. A lens may be configured to operate in at least a first configuration and a second configuration. The lens may have a first filter over a first portion of the lens and a second filter over a second portion of the lens. In the first configuration, a third filter may operate with the lens and the second filter to allow visible light from a first object located beyond a predetermined distance from the lens to pass and be focused on a sensor for image acquisition. In the second configuration, a fourth filter may operate with the lens and the first filter to allow IR light from a second object located within the predetermined distance to pass and be focused on the sensor for image acquisition.
