ABSTRACT:
Laser projection systems are provided comprising a laser source, scanning optics, beam splitting optics, and a scanning controller. According to one embodiment, the laser source is configured to produce at least two optical beams having different emission wavelength spectrums. The beam splitting optics are positioned downstream of the scanning optics and are configured to generate wavelength-dependent spatial misalignment of the two optical beams in the image plane by splitting the two optical beams into spatially misaligned propagating axes. According to another embodiment of the present invention, the beam splitting optics are positioned downstream of the scanning optics and are configured to generate polarization-dependent spatial misalignment of the two optical beams.
