The objective of the course is two-fold:
1) Provide the basic tools of geometrical radiometry and colorimetry, which are needed for designing electro-optical detection systems (flux collectors or image forming systems). At the end of this course future engineers or scientists will be able to specify and characterize the optical and the optoelectronic components of subsystems such as: light sources, propagating media, surfaces, optical components, detectors. For this goal, the black body model and the description of the scattering and absorption phenomena are also addressed.
2) Knowing the main characteristics of optronic detectors. Understand and answer specifications using a system approach that is generally followed by project leaders or R&D engineers. Optimize the design of optical sensors, by evaluating their signal to noise ratio, basic parameter on system performance. The specific case of digital cameras with their performances and technological limitations will be treated.
