Signal characterization of oscillators and laser illuminated material
Résumé
Several issues come together when it comes to getting to know oscillators better. Knowing how to accurately assess the performance of state-of-the-art oscillators is fundamental [1 – 4]. This is also true when we seek to understand, for example, how a material reacts when illuminated by a sufficiently powerful laser signal so as to cause the re-emission of another signal which is characteristic of the properties of the material that we want to determine [5]. There is also an important point that must be addressed. When giving the result obtained with regard to frequencies, it all makes sense if and only if we are able to assess what measurement uncertainty will be associated with the result. It is therefore also a question here of the estimation of uncertainty for complex system engineering in optics and electronics [6 – 10]. It is a major point for such complex systems.
