We describe a Doppler imager able to measure the velocity field at surface of planets of the Solar System, specially designed for atmospheric dynamics study and oscillation detection. It was developed in the frame of the JOVIAL network for the study of internal structure of the giant planets (Gonçalves et al, 2019). The instrument is based on a Mach-Zehnder interferometer and monitors the Doppler shift of reflected solar spectral lines at the surface of the planets, giving access to the local velocity field. We show the performances reached by the instrument for the measurement of zonal and vertical winds in the atmosphere of Jupiter. We also see that the observations are affected by the quality of the image, and in particular by atmospheric turbulence. In order to overcome this issue, we developed an Adaptive Optics system which can work on a field of 60 arcsec, wide enough for partial corrections on Jupiter. This system not only improves the size and stability of the PSF, but might also provide useful information for an a posteriori correction of the Doppler data.
