Abstract
This optical detector unit is a hybrid unit operating in a given wavelength range and includes, superposed, a first optical detector comprising detecting elements formed in a semiconductor structure, each detecting element being intended for converting a flux of incident photons into an electrical signal; and a first read out circuit, for reading the electrical signal from each detecting element. The optical detector unit furthermore has an imaging system with a second optical detector intended for increasing the operating wavelength range of the optical detector unit and a second read out circuit for reading the electrical signals from the detecting elements of the second optical detector.The first and second read out circuit are integrated together, so as to form a common read out circuit.
