The invention is directed to a method for optoelectronic distance measurement and a measurement device based on this method, in which two light emitters, particularly laser emitters and two photodiode receivers are used for calibration. Said measurements are centered on M measurement points, the M measurements of the second image corresponding to the M measurements of the first image by the fact that the M measurement points of the second image correspond to the M measurement points of the first image. The expansion system further includes a heat exchanger coupled to the pump and configured to vaporize the condensed working fluid received from the pump. For example, an instantaneous size of the receiving data buffer may be measured, and if measured multiple times, may be averaged over a time period. The migration may occur manually or automatically on a migratable services framework.
