Optical device for controlling the orientation and position of a surface in motion by the interferometric and secondary source generated by interaction of the laser - material comprising such a device.

摘要

The present invention relates to an optical device for controlling the orientation and position of a surface in motion (10) by the measurement interferometer, characterized in that it comprises: - a laser beam of the control (11), separated into two arms, one of which is a reference beam, which is fixed, and the other is a beam of analysis (12) is reflected by the surface in motion and the mobile; - means for making the said beams interfere reference and analysis so as to generate interference fringes; - means (16) of the camera type to be imaged the interference fringes, bearing the information of position and orientation of said surface; - of the analysis means (17) of the images of interference; - means (18) for generating a feedback loop for controlling the orientation and position of said surface in motion from the analysis of the signal carrying information. The present invention also relates to a laser source secondary generated by the illumination and destruction of a target and integrating the control device of the invention.
