20110174981 | Photodiode Array, Radiation Detector and Method for Producing Such a Photodiode Array And Such A Radiation Detector - A photodiode array for a radiation detector is disclosed, including a multiplicity of photodiodes arranged in a structured fashion, the photodiodes respectively having an active pixel region for converting light into electrical signals. In at least one embodiment, a transparent oxide layer with a refractive index comparable to the photodiodes is arranged on the active pixel region of at least some of the photodiodes on a side of the photodiode array provided for arranging a scintillator array. Compared to known photodiode arrays, the oxide layer replaces an adhesive. As a result of equalizing the refractive indices, light incident on the interface between the oxide layer and the photodiode array is refracted or reflected to a lesser extent. This reduces the optical crosstalk between adjacent pixels. Moreover, the active pixel regions of the photodiodes become optically visible as a result of the oxide layer. This therefore provides conditions for precisely aligning the photodiode array relative to the scintillator array by way of optical monitoring. Overall, compared to known radiation detectors, this procedure can increase the effective light yield. At least one embodiment of the invention moreover relates to a corresponding method for producing such a photodiode array and such a radiation detector. | 07-21-2011 |
