Abstract
Use the law of refraction of light for theoretical analysis of sunlight incident Fresnel lens, summary of the relationship between Fresnel lens solar light beam convergence characteristics and beam incident angle,beam incident position.Through the analysis of the calculation and experimental, to obtain a variety of incident angle lens center and best gathering focal spot the size of the data.Discuss the incident angle, incident location,the relationship between convergence center and focal spot size.For the sun acquisition system of the light from the sun and optical fiber coupling design do sufficient theory design basis.
