Abstract
An image detector using arrays of photodiodes, and in particular to a radiological image detector. In the image detector, all the photodiodes of one and the same array are linked to adapter amplifiers embodied in the form of at least one integrated circuit. In each integrated circuit, an adapter amplifier, to which no photodiode is linked, delivers a voltage serving as a reference to define a bias voltage to be applied to the photodiodes. This arrangement makes it possible in particular to associate photosensitive arrays with amplifiers exhibiting different voltage thresholds.
