Claim:
1. A method for analyzing an object using a particle beam apparatus, the particle beam apparatus having at least one beam generator for generating a particle beam with charged particles, at least one objective lens for focusing the particle beam onto the object, wherein interaction particles are generated and/or interaction radiation is generated in the case of an interaction between the particle beam and the object, at least one vacuum region, in which at least one detector is arranged to detect the interaction particles and/or the interaction radiation, wherein the detector has at least one detection surface, wherein a multiplicity of detection units are arranged at the detection surface, wherein each detection unit of the multiplicity of detection units is individually actuatable and readable by way of a control device, at least one data memory, in which information is stored, wherein the information comprises information about an interaction behavior of the particle beam with the material of the object and/or information about solid angle regions, in which the interaction particles propagate after the generation thereof and/or into which the interaction radiation is emitted after the generation thereof, and at least one analysis unit for analyzing the object, the method comprising: identifying at least one first group of detection units from the multiplicity of detection units using the information stored in the data memory; forming a first detector segment from the first group of detection units; loading information about the first detector segment into the control device; guiding the particle beam onto the object and scanning the object using the particle beam; detecting the interaction particles and/or interaction radiation with the detector, wherein a first detector segment signal is read from the first detector segment; generating a representation of the object using the first detector segment signal; and analyzing the object using the representation of the object in the analysis unit.
