Claim:
1. A scanning microscope comprising: a stage for holding a sample and a sensor array having a plurality of predefined substantially linear detection regions; a scan mechanism configured to translate the stage holding the sample between at least two axial positions each associated with a corresponding predefined region of the plurality of predefined substantially linear detection regions, wherein after the translation actual orientation and transverse position of the stage deviates from ideal orientation and transverse position of the stage; a probing system configured to probe the corresponding predefined region, and comprising at least one optical element and a photosensor having a readout extending in a sensor direction transverse to the ideal orientation; a plurality of position sensors configured to measure the actual orientation and transverse position by measuring a distance between a respective reference point on the stage and a corresponding position on a fixed frame of reference inline with the corresponding predefined region; a controller configured to control the probing system to correct for the deviation of the stage from the ideal orientation and transverse position as a function of the measured distance to assure probing of the corresponding predefined region; wherein the controller is configured to correct a non-straightness of the translation of the stage.
