High Performance FOV Switching Mechanism Design for an Infrared Zoom Lens
This paper presents the design and implementation of a prototype dual FOV (field-of-view) zoom lens mechanism. The infrared zoom lens uses a permanent magnet DC motor for the motion driver and a microcontroller as the controller. Through the cooperation of two major sensor signals, a shaft encoder a...
