We present a monostatic system for characterization of optical turbulence along a horizontal path in the lower atmospheric boundary layer. The apparatus is a telescope focusing a beam into a retro-reflector and collecting the reflected beam. Two approaches for estimation of the Fried's parameter are presented: Zernike mode variances and the modulation transfer function.
