Patent ID: 7460216

Claim:
Device for measuring topographies and strains of at least one surface of a sample, comprising: first measuring means for measuring topographies and movements that are perpendicular to a plane defined by a surface of the sample, the first measuring means utilizing structured illumination, second measuring means for measuring strains that are in the plane defined by the surface of the sample, the second measuring means utilizing image correlation, the first measuring means and the second measuring means utilizing at least one common light detection camera, heating means and means for measuring the temperature of the sample, wherein the first measuring means comprise means for projecting composite images by illuminating the surface with a sequence of images, each image comprising a periodic pattern, the periodic patterns of the different images of the sequence of images respectively presenting pitches of different periodicities, the device comprises an enclosure transparent at least locally to visible light, wherein the sample is arranged, the heating means comprising at least one infrared emitter creating an infrared light not detected by the camera.
