BiasedBSM models both the mechanical dynamics and the optical effects (applied tilts) of a beam steering mirror. The mirror is modeled as a two-axis critically damped harmonic oscillator. 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. As of WaveTrain v2007A, BiasedBSM is redundant to BeamSteeringMirror and should be replaced. It is provided for backwards compatibility.
