Abstract

The invention relates to a modulatable infrared emitter comprising a MEMS heating element and an actuator, wherein the actuator triggers shape and/or structure changes of the MEMS heating element. Said change in shape and/or structure of the MEMS heating element may vary the ratio of the emitting area to the total area, thereby producing a change in intensity of the emitted infrared beam. The invention further relates to a manufacturing method for the infrared emitter, a method for modulated emission of infrared radiation using the infrared emitter, and preferred uses of the infrared emitter. In further preferred aspects the invention relates to a system comprising the infrared emitter and a control device for regulating the actuator.
