BeamSteeringMirror_dmk models both the mechanical dynamics and the optical effects (applied tilts) of a beam steering mirror. The mirror is modeled as a two-axis damped harmonic oscillator (not necessarily critically damped). Tilt is given in radians of optical tilt, equal to twice the tilt of the mirror surface. Tilts applied to the reference wavefront, as opposed to putting them into the complex field. An idealized tilt sensor (actually just a delay) measures the optical tilts and makes them available as an output

mtilt	float	mass (m*xdotdot + d*xdot + k*x =c, where x = actuator position, c= actuator command)	pow(timeConstant,2.0)
ktilt	float	spring constant (m*xdotdot + d*xdot + k*x =c, where x = actuator position, c= actuator command)	1.0
pos0	Vector<float>	Initial position	Vector()
vel0	Vector<float>	Initial velocity	Vector()
acc0	Vector<float>	Initial acceleration (command)	Vector()
