MODELING THE EMISSION INTENSITY OF AN IR EMITTER BY VARYING THE EMISSION SURFACE

摘要

The invention relates to an infrared emitter which can be modulated, comprising a MEMS heating element and an actuator. The actuator produces changes in the shape and/or structure of the MEMS heating element. By virtue of the change in shape and/or structure of the MEMS element, the ratio of the emission surface area to the total surface area can be varied, whereby a change in the intensity of the emitted infrared radiation is produced. The invention additionally relates to a method for producing the infrared emitter, to a method for a modulated emission of infrared radiation using the infrared emitter, and to preferred applications of the infrared emitter. The invention also preferably relates to a system comprising the infrared emitter and to a controller for regulating the actuator.
