    摘要: A lens position sensor for infrared or other types of cameras, which is particularly useful in lens assemblies that have relatively limited axial travel between near field and far field lens focus positions. The camera includes a magnet or other stimulator coupled to a rotatable lens that extends within a magnet plane where the magnet plane is not normal to the optical axis of the lens. A magnetic or other sensor senses the position of the magnet, which is indicative of the lens position.
