Description
Several techniques (based in particular on laser systems) are used to monitor the curvature of reflective objects in a non invasive way and in real time with high precision. However, their implementation is usually complex and it involves expensive devices which can only work in specific experimental conditions.
Our solution: 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.
Applications
- Real time process or post-process monitoring (example: annealing, epitaxial growth…)
- Numerous possible application domains:
- Astronomy
- Aerospace
- Automotive
- Health
