Abstract
A calibration system for calibrating a tilt angle of the fast steering mirror includes a position sensing device configured to generate a beam of electromagnetic radiation, and a diffractive optical element, positioned between the position sensing device and the fast steering mirror, the diffractive optical element being configured to divide the input beam into a plurality of output beams directed to the fast steering mirror. The position sensing device is configured to determine a tilt angle of the fast steering mirror. A method to calibrate a tilt angle of the fast steering mirror is further disclosed.

A calibration system for calibrating a tilt angle of fast steering mirror, the calibration system comprising:
- a position sensing device configured to generate a beam of electromagnetic radiation;
- and
- a diffractive optical element, positioned between the position sensing device and the fast steering mirror, the diffractive optical element being configured to divide the input beam into a plurality of output beams directed to the fast steering mirror,
- wherein the position sensing device is configured to determine a tilt angle of the fast steering mirror.
A method to calibrate a tilt angle of fast steering mirror, the method comprising:
- generating an input beam of electromagnetic radiation from a position sensing device;
- dividing the input beam into a plurality of output beams directed to the fast steering mirror;
- and
- determining a tilt angle of the fast steering mirror based on a reflection of the output beams by the fast steering mirror.
