Abstract
Multiple electron beam optics that includes a detection unit that comprises an array of sensors, and a cross talk reduction unit. For each sensor of multiple sensors of the array of sensors: (i) the sensor includes an aperture and a sensing region that is configured to sense relevant backscattered electrons, the relevant backscattered electrons are emitted from the sample as a result of an illumination of the sample with a primary electron beam that is associated with the sensor and passed through the aperture; and (ii) the crosstalk reduction unit is configured to at least partially prevent a detection, by the sensor, of cross talk backscattered electrons, the cross talk backscattered electrons are emitted from the sample as result of an illumination of the sample by one or more primary beams not associated with the sensor.
