Claim 5:
6. A method for operating a laser projection device configured to perform trajectory optimization, the method comprising:
device;
supplying power from a power source to a power amplifier of the laser projection emitting a laser beam towards a surface of an object with a laser source;
calculating with a trajectory control module one or more parameters for a projection trajectory of the laser beam;
controlling the projection of the laser beam along the projection trajectory with a beam steering unit based at least in part on the calculated one or more parameters, the beam steering unit having at least one galvanometer with a mirror coupled thereto;
wherein calculating the one or more parameters comprises calculating a refresh rate for the laser beam based on a flicker-free threshold for a particular wavelength; and
switching a switching current mode power amplifier, wherein the output of the switching current mode power amplifier is determined based on a configurable effective duty cycle to control an effective voltage to the at least one galvanometer.
