Device for measuring the curvature and defects of a reflective surface

DESCRIPTION

The system presented herein consists of a portable device made of simple optical elements which can work in any environment.
It enables one to measure the curvature and defects of any surface which exhibits a minimum level of reflectivity in an absolute way
and with high precision, over a long period of time without requiring further optical alignments.

• System composed of a luminous object, a camera with a lens, a beam splitter and an analysis software
• Formation of the virtual image of the object through the surface and analysis of the variations of the formed image in real time
• Possibility of using the system with the luminous object and the camera placed at any incidence angle with respect to the surface perpendicular
• Absolute measurement of curvature in real time, surface 3D reconstruction

APPLICATIONS

• Real time process or post-process monitoring (example: annealing, epitaxial growth…)
• Numerous possible application domains:
  
  • Astronomy
  • Aerospace
  • Automotive
  • Health…
