Abstract
A device for detecting energy beam is provided. The device comprises a carbon nanotube structure, a support structure and an infrared detector. The carbon nanotube structure comprises a plurality of carbon nanotubes, and an extending direction of each carbon nanotube is parallel to a direction of an energy beam to be detected. The support structure is configured to support the carbon nanotube structure, and make a portion of the carbon nanotube structure suspended in the air. The infrared detector is located below and spaced apart from the carbon nanotube structure. The infrared detector is configured to detect a temperature of a suspended portion of the carbon nanotube structure, and image according to a temperature distribution of the carbon nanotube structure. A method for detecting energy beam is also provided.
