Claim 0:
1. Modulatable infrared emitter comprising:
a heating element, and
an actuator
wherein the heating element is a MEMS heating element comprising heatable regions for emitting infrared radiation in an emission direction which is substantially perpendicular to a total area of the MEMS heating element, the projection of the heatable regions in the emission direction forming an emission area and the area spanned by the MEMS heating element forming the total area, and the actuator being configured to change the shape and/or structure of the MEMS heating element between a first and a second state, so that the ratio of the emission area to the total area of the MEMS heating element is smaller by at least a factor of 2 in the first state than in the second state.
