Scientific paper

A 100×100 photodiode array of the Reticon type is used to measure velocity fields in the solar atmosphere at the Locarno Observatory of the University of Göttingen. A 16 bit microprocessor serves to control the array and the telescope. Several tests were performed to determine the properties of the new measurement system. After correction for the dark current and the flat field the fixed pattern noise is less than 1%. Averaging over 5 rows of the array, which corresponds to a spatial averaging over 2arcsec.5, allows to determine velocities with a precision of ±25 m/s.
