In a non image space telecentric lens (left) ray cones strike the detector at different angles; in a bi-telecentric lens (right) ray cones are parallel and reach the image sensor in a way independent on the field position. Moreover, in a telecentric lens the principal ray intercept doesn'...
Optical Lens System for Taking Image An optical lens system for taking image comprises, in order from the object side to the image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive p... HC Tang,Lin,...

TELECENTRIC LENS SYSTEM FOR PROVIDING AN IMAGE WITH THE PRINCIPAL RAYS PARALLEL TO THE OPTICAL AXIS AND NORMAL TO THE FOCAL PLANEDONALD C. DILWORTH
We propose a method for accurately calibrating a telecentric structured light system consisting of a camera attached to a bilateral telecentric lens and a pin-hole projector. The proposed method can be split into two parts: axial calibration and transver
