In opticaldesign, the designer's experience is critical. Indeed, an experienced opticaldesigner will often choose a better starting point for optimization than an inexperienced one. Most of the time, lens design software use a local optimization algorithm, which is why the starting point is so important to get an excellent optical system. We present here an alternative to the classical opticaldesign method and a solution to reduce the impact of the designer's experience. Our alternative couples the Simultaneous Multiple Surfaces (SMS) method, introduced by Benitez and Minano with optimization in Zemax OpticStudio. The SMS method is a direct construction method of opticalsystems without optical aberrations for as many field points as the system contains surfaces. This method can deal with both aspheric and freeform opticalsystems depending on the dimension of the method implemented. Our implementation of the SMS method can designopticalsystems with three surfaces. We use the SMS method to define a freeform system with an F-number of 0.85. Then, we use this fast freeform system as a starting point to perform further optimization in Zemax OpticStudio. Finally, we achieve to design two diffraction-limited freeform systems, one over a square field of view of +/- 30 degrees and another over a rectangular field of view of +/- 33 degrees x +/- 26 degrees.
Safety and security analyses are crucial for developing safety-critical cyber-physical systems as they can identify potential design defects and vulnerabilities. The Architecture Analysis and design Language (AADL) is...
