An infrared detector may be configured to detect a wide bandwidth of infrared spectrum using a broadband surface plasmon resonator. The infrared detector may include a substrate; a thermistor member disposed spaced from the substrate, the thermistor member having a resistance value that varies according to temperature; a resonator disposed on the thermistor member, the resonator configured to generate surface plasmon resonance; a pair of thermal legs configured to support the thermistor member such that the thermistor member is disposed spaced from the substrate; and a pair of conductive lead wires respectively disposed on the pair of thermal legs. The conductive lead wires may be configured to transmit signals to the substrate from the thermistor member and the resonator. The resonator may have a plurality of resonant frequencies and be configured to generate the surface plasmon resonance in a plurality of resonant modes.

Infrared detector including broadband surface plasmon resonator

An infrared detector capable of detecting an infrared spectrum having a wide bandwidth using a broadband light absorber. The infrared detector including a substrate, a light absorber disposed apart from the substrate at a distance, and a pair of thermal legs configured to support the light absorber such that the light absorber is spaced apart from the substrate by the distance. The light absorber includes at least one thermistor layer having a resistance value that varies according to temperature and at least two resonator layers disposed on at least one of upper and lower surfaces of the at least one thermistor layer.

Infrared detector including broadband light absorber

An infrared detector includes at least one infrared absorber provided on a substrate and a plurality of thermocouples. The at least one infrared absorber may include one of a plasmonic resonator and a metamaterial resonator. The plurality of thermocouples may be configured to generate electromotive forces in response to thermal energy generated by the at least one infrared absorber.

Infrared detector and infrared image sensor including the same

A recording mode control method for combined video appliances whereby necessary information of a specific channel broadcasting signal may be selectively recorded, and in the event that the specific channel broadcasting signal has unnecessary information, another channel broadcasting signal may be displayed on a screen by a user. If a new channel selection data is inputted during the recording of a specific channel broadcasting signal, the specific channel recording mode is switched to a stop mode or a still mode and the presently selected channel broadcasting signal is displayed on a screen. Thereafter, if the channel selection data of the specific channel broadcasting signal previously recorded is inputted again, the recording mode for the specific channel is automatically resumed and the specific channel broadcasting signal is recorded again.
