Image sensors having radiation detectors and masks

Abstract

Disclosed herein is an image sensor comprising: a plurality of radiation detectors; a mask with a plurality of radiation transmitting zones and a radiation blocking zone; and an actuator configured to move the plurality of radiation detectors from a first position to a second position and to move the mask from a third position to a fourth position; wherein while the radiation detectors are at the first position and the mask is at the third position and while the radiation detectors are at the second position and the mask is at the fourth position, the radiation blocking zone blocks radiation from a radiation source that would otherwise incident on a dead zone of the image sensor and the radiation transmitting zones allow at least a portion of radiation from the radiation source that would incident on active areas of the image sensor to pass through.
