Claim Text:
1. A system for measuring intensity distribution of light comprising: a carbon nanotube array configured to absorb photons of a light source and to radiate radiation light, wherein the carbon nanotube array is in a vacuum environment, the carbon nanotube array is placed on a substrate, an entire first surface of the substrate is in contact with the carbon nanotube array, the carbon nanotube array is between the substrate and the light source, and the carbon nanotube array comprises a plurality of carbon nanotubes substantially perpendicular to the first surface of the substrate; and an imaging element spaced from the carbon nanotube array, the imaging element being configured to image the radiation light from the carbon nanotube array, wherein the light source is located on a first side of the carbon nanotube array and the imaging element is located on a second side of the carbon nanotube array opposite to the first side.
