H. Ohba and S. Komatsu: Optical wavefront sensing using a 2-dimensional diffraction grating: Application to biological microscopy, Optics and Lasers in Biomedicine and Culture (Proc. Optics Within Life Sciences V) (Springer-Verlag, July 2000), 340-343.

We developed a new wavefront sensor using a 2-dimensional diffraction grating with which we succesfully measured a light wavefront distorted by thermal turbulence. In this paper, we improve the lateral resolution of the wavefront sensor and discuss the application of the sensor to biological microscopy.
