Astronomical seeing measurements are usually made at a single wavelength and extrapolated to other wavelengths of interest using scaling laws that assume a specific energy spectrum for the atmospheric turbulence. We describe a variation of the Differential Image Motion Monitor system that provides a measure of the seeing and evaluation of the scaling law by simultaneously measuring the image motion at three different wavelengths.
