Title: David Couder: Innovator in Radiation Detection Technology

Introduction

David Couder is a notable inventor based in Grenoble, France. He has made significant contributions to the field of radiation detection technology, holding three patents that showcase his innovative approach to controlling light-sensitive devices.

Latest Patents

One of his latest patents is a method for controlling a photodetector by automatically detecting incident radiation. This method involves a light-sensitive device, such as a digital X-ray detector, which includes an array of light-sensitive points. Each point is connected to a column conductor and line conductors, featuring a light-sensitive element that converts photon flux into electrical charges. The method utilizes a capacitor for cross-coupling between the drain and source of each transistor in the off state, allowing for potential variation upon receiving photons. The process includes comparing this potential variation with a threshold to read the light-sensitive points when the comparison is positive.

Another significant patent by Couder is a method of fabricating a radiation detector. This invention relates to a photosensitive sensor assembly and a scintillator that converts radiation into a form detectable by the sensor assembly. The scintillator is bonded to the sensor assembly, which consists of a substrate and several attached sensors. The method outlines a series of operations to effectively link these components.
