We proposed two schemes of compact tunable liquid crystal astigmatic plate. The device is a modal spatial light modulator with a specific electrodes configuration. Numerical simulations of operation of the device showed its capability to form astigmatic wave front describing by Z 22 and Z 2-2 Zernike polynomials and also by their superposition. Various modes of operation of LC device are considered. The capability of operation as a truncated axicon is shown.
