Abstract
A sequence of individual images is acquired by imaging the sample through imaging optics onto an image sensor. For the acquisition of each individual image, the sample is provided with a marker pattern, in which individual markers can be imaged in the form of spatially separable light distributions through the imaging onto the image sensor. The centroid positions of the light distributions are determined and superimposed to form a complete image of the sample. According to the present invention, an image-drift-inducing temperature value (ΔT1, ΔT2, . . . , ΔTn) is measured during the acquisition of the sequence of individual images. A temperature-dependent drift value (ΔX1, ΔX2, . . . , ΔXn; ΔY1, ΔY2, . . . , ΔYn) is correlated to the image-drift-inducing temperature value (ΔT1, ΔT2, . . . , ΔTn) based on predetermined correlation data. The determined centroid positions are corrected based on the drift value (ΔX1, ΔX2, . . . , ΔXn; ΔY1, ΔY2, . . . , ΔYn).
