Patent number: 8981319Abstract: A system for measuring intensity distribution of light includes a carbon nanotube array located on a surface of a substrate, a reflector and an imaging element. The carbon nanotube array absorbs photons of a light source and radiates a visible light. The reflector is used to reflect the visible light, and the reflector is spaced from the carbon nanotube array. The carbon nanotube array is located between the reflector and the substrate. The imaging element is used to image the visible light. The imaging element is spaced from the substrate.Type: GrantFiled: December 28, 2012Date of Patent: March 17, 2015Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Jun Zhu, Jing-Lei Zhu, Kai-Li Jiang, Chen Feng, Ji-Qing Wei, Guo-Fan Jin, Shou-Shan Fan

Patent number: 8830453Abstract: A method for measuring intensity distribution of light includes a step of providing a carbon nanotube array located on a surface of a substrate. The carbon nanotube array has a top surface away from the substrate. The carbon nanotube array with the substrate is located in an inertia environment or a vacuum environment. A light source irradiates the top surface of the carbon nanotube array, to make the carbon nanotube array radiate a visible light. A reflector is provided, and the visible light is reflected by the reflector. An imaging element images the visible light reflected by the reflector, to obtain an intensity distribution of the light source.Type: GrantFiled: December 28, 2012Date of Patent: September 9, 2014Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Jun Zhu, Jing-Lei Zhu, Kai-Li Jiang, Chen Feng, Ji-Qing Wei, Guo-Fan Jin, Shou-Shan Fan
