The Technology
Polarization-sensitive cameras are in mass production for integration in products at various markets. Calibration and quality testing are important when using industrial cameras. Polarization introduces new sensitivity concerns in calibration. For specialized research-level cameras, calibration systems in the world are built per lab and project in-house. These solutions are not applicable for mass production and are lacking automation and generally do not calibrate some important effects, such as:
§ Birefringence due to stress on optical components
§ Polarization-dependent point spread function (PSF)
§ Light-incidence sensitivity
This invention is an automatic calibration system and algorithms for polarization-sensitive cameras. It addresses the practical challenges arising from polarimetry while providing industrial merits: scalability, repeatability, and ease of use.
Advantages:
This new technology addresses the challenges of multiple degrees of freedom, targeting numerous variables compared to traditional calibration, requiring automation for fast and scalable sampling. The automation and the solution of practical polarization-related challenges make it the only solution applicable for high-quality calibration in mass-production of modern polarization sensors.
Applications:
- Machine vision
- Medical diagnostics and Microscopy
- Interferometry
- Automotive industry – advanced driver-assistance systems (ADAS) systems
- Mobile devices including cameras based on meta-surface lenses
