We are conducting a concept study on a wide field of regard (FoR) Multi-Object Adaptive Optics (MOAO) system for Thirty Meter Telescope (TMT-AGE: TMT-Analyzer for Galaxies in the Early universe). The main science target of TMT-AGE is high-redshift galaxies. Considering the small number density of high-redshift galaxies, enlarging the FoR of an MOAO system up to around 100 is critical. In order to increase the FoR of an MOAO system, we propose a new tomographic reconstruction method. In the new method, we use atmospheric wind profiles and WFS measurements at previous time steps to increase the number of virtual measurement points of atmospheric turbulence layers for tomographic reconstruction. We present the results of numerical simulations with the new tomography method. The simulations show the new method can reduce the tomographic error in a wide FoR.
