Simulation of the wavefront sensing of the active primary mirror system for the 2.1-m telescope of the SPMO

In this work we present a simulation of the wave-front sensing of the active primary mirror support for the 2.1-m telescope of the San Pedro Mártir's Observatory by Non-Linear Curvature Wave-front Sensing. The active cell is going to be tested by changing its actuator values. In each active cell state, defocused pupil images from both sides of the focal plane will be simulated and phase retrieval will be performed. The algorithm employed to reconstruct the wave-front will be discussed, as well as the sensitivity obtained in our simulation.
