Abstract:	摘要： Light-emitting diodes are common light sources in modern lighting. The optical distribution of an LED package and the bidirectional scattering distribution function (BSDF) of diffusing optical components are important factors in lighting design. This paper proposes an innovative method of measuring both the optical distribution of LEDs and BSDF quickly. The proposed method uses a 2-D screen and a camera to capture the illumination on a screen, and acquires the whole-field optical distribution by synthesizing the images on the screen in different angles. This paper presents theoretical calculations and experimental results demonstrating the construction of the BSDF. 其他題名： Opt Express 出版者： United States: Optica Publishing Group 出版日期： 2012-01-16 出處： Optics Express, 2012-01, Vol.20 (2), p.1268- 資源來源： Optica Publishing Group Journals 識別號： ISSN: 1094-4087 識別號： EISSN: 1094-4087 識別號： DOI: 10.1364/oe.20.001268 識別號： PMID: 22274472
