摘要

The present invention relates to a pixel detector (10), comprising a semiconductor sensor layer (12), in which charges can be generated upon interaction with particles to be detected. The semiconductor layer defines an X-Y-plane and has a thickness extending in Z-direction. The detector further comprises a read-out electronics layer (14) connected to said semiconductor layer (12), said read-out electronics layer (14) comprising an array of read-out circuits (20) for detecting signals indicative of charges generated in a corresponding volume of said semiconductor sensor layer (12). The neighboring read-out circuits (20) are connected by a relative timing circuit configured to determine time difference information between signals detected at said neighboring read-out circuits (20). The time difference information is indicative of a difference in the Z-components of the locations of charge generations in the corresponding neighboring sensor volumes caused by a particle trajectory that is inclined with respect to the X-Y-plane.
