Ronchi test simulator for concave mirrors

Parameters description:
roc - radius of curvature in mm
diameter - mirror diameter in mm
conic - mirror conic constant / conicity
grating_lines - ronchi grating parameter - lines per mm
ronchi_phase - vertical shift of ronchi grating expressed as a phase shift of sine function 0 - Pi
delta - distance of ronchi grating from paraxial focus / radius of curvature in mm
