Patent attributes
A modular infrared radiation source is provided, including a support provided with a flat wall; a membrane including front and rear faces essentially parallel to each other, the membrane being configured to emit infrared radiation by the front and rear faces, and being maintained in suspension with respect to the support, the rear face facing the wall at a distance therefrom, the wall being configured to reflect infrared radiation; and an electrostatic actuator including first and second electrodes arranged facing each other, configured to vary the distance by application of a difference in electrostatic potential between the first and second electrodes, the membrane and the electrostatic actuator arranged such that, for each wavelength, infrared radiation emitted by the rear face is reflected by the wall, passes through the membrane from the rear face to the front face, and interferes with infrared radiation emitted by the front face.
