LERITY has extensive know-how and expertise in the design of optronic systems for applications in severe environments: temperature, shocks and vibrations and electromagnetic.

In order to significantly increase the reliability of the systems, our approach consists on the one hand in replacing by innovative solutions all the mechanisms and more generally all the moving parts traditionally used in optronic systems, and on the other hand in minimizing the number of product parts. With this approach it is easy to ensure an excellent electrical continuity between the different parts and consequently a good behavior against electromagnetic aggression

The acquired expertise, validated by qualification tests and demonstration of reliability integrating the real environmental conditions of the products, concerns in particular the following solutions:

• LCD-based electronic iris to replace mechanical iris
• Passive athermalization of optics to eliminate focusing mechanisms
• Multi sensor concept combined with fixed focal length lenses to replace motorized zooms
• Consideration of EMC constraints in the design from the preliminary design phases
• Dedicated real time signal processing
