Eta Car is a unique object for studying the massive stellar winds in a wind-collision binary during the LBV phase. X-ray studies show that there is a phase-dependent wind collision zone in Eta Car. We present velocity-resolved Eta Car images reconstructed in more than 100 different spectral channels distributed across the Brackett Gamma emission line. Interferometry can provide information on the orbit, the primary wind, and the wind collision. The obtained images of Eta Car's primary star wind and wind collision zone have a spatial resolution of 6 mas (14 au) and high spectral resolution of 12000. For example, at wavelengths corresponding to radial velocities of -140 to -376 km/s, the intensity distribution has a fan-shaped structure. The fan extends 8.0 mas (19 au) to the southeast and 5.8 mas (14 au) to the northwest. The shapes of the velocity-resolved intensity distributions suggest that the obtained images are the first images of the innermost wind collision zone. Therefore, the observations provide time- and velocity-dependent image structures that can be used to test 3-D hydrodynamical models of the massive interacting winds of Eta Car.
