Title:
How to control an optical power detector by detecting incidence radiation automatically
Document Type and Number:
Japanese Patent JP6165724
Kind Code:
B2
Abstract:
A method is provided for controlling a light-sensitive device, for example, a digital X-ray detector including an array of light-sensitive points. The light-sensitive device includes a column conductor, line conductors, and light-sensitive points. Each light-sensitive point is connected between the column conductor and one of the line conductors, and includes a light-sensitive element converting a photon flux into electrical charges, and a transistor transferring the electrical charges to the column conductor based on control of a signal received by the corresponding line conductor. The method depends on the presence of a capacitor for cross-coupling between the drain and source of each transistor in the off state. The capacitor provides a potential variation to the column conductor upon receiving photons. The method comprises comparing the potential variation with a threshold, and reading the light-sensitive points in the event that the result of the comparison is positive.
