Abstract
An optical system is provided that uses unwanted light to perform autofocus functions. More particularly, one or more optical elements may be used to reflect unwanted light to one or more secondary image sensors associated with an autofocus function. Such unwanted light may include, for example, IR, UV, or visible light not necessary for creating a resulting image detected by a primary sensor.
