Micro-Optics Label Receiving System Based on Annular Aperture Ultra-Thin Lens
The micro-optics label receiving system is designed, a large aperture and long focal length lens called annular aperture ultra-thin lens which is used as mobile phone lens of system receiving terminal is proposed, a fourreflection folded annular aperture lens is designed with Zemax. Front and rear surfaces of lens are annual aspheric mirrors, the outer diameter of lens is 28 mm, the effective focal length is 36 mm and the thickness of lens is 7.6 mm. This lens has large effective focal length, long aperture and ultra-thin characteristics in limited thickness and weight. Thus, a long distance receiving of micro-optical label with the mobile phone is obtained. Furthermore, a image distortion correction program is developed on VC 6.0 platform based on the OpenCV computer vision library, the radial distortion of receiving image simulation is modified and decoded accurately in order to obtaining the required information.
