Abstract
According to certain embodiments, an electro-magnetic radiation detector includes a sensor coupled to multiple nanostructures and an electro-magnetic radiation indicating device. The nanostructures are adapted to absorb electro-magnetic energy and generate heat according to the absorbed electro-magnetic energy. The sensor is adapted to measure the heat generated by the plurality of nanostructures and to generate a first signal according to the measured heat. The electro-magnetic radiation indicating device is operable to receive the signal from the sensor and indicate a level of electro-magnetic energy absorbed by the plurality of nanostructures according to the received signal.
