Abstract: Embodiments disclosed herein include pre-terminated fiber optic connector sub-assemblies, and related fiber optic connectors, cables, and methods. In certain embodiments, an optical fiber stub is pre-installed in a ferrule bore of a ferrule of a fiber optic connector sub-assembly, to provide the pre-terminated fiber optic connector sub-assembly. The optical fiber stub can be pre-installed in the ferrule bore prior to termination of the fiber optic connector sub-assembly. Because the pre-terminated optical fiber stub disposed in the ferrule bore is not directly accessible through a ferrule body of the ferrule when a field optical fiber is disposed in the ferrule bore for fusion splicing, the ferrule has properties that allow thermal energy to be directed through the ferrule body into the ferrule bore. In this manner, the optical fiber stub pre-installed in the ferrule bore can be fusion spliced with the field optical fiber to terminate a fiber optic cable.

Abstract: A laser projection system is provided comprising a light source, a phase retarding element, and a beam scanning element. The light source comprises at least one frequency-converted laser source comprising a wavelength-tunable laser diode and a wavelength conversion device. The phase retarding element is configured to resolve the polarization of a frequency-converted laser beam into two orthogonal linearly polarized components such that one component of polarization is phase delayed relative to the other. Frequency-converted laser beam polarization in the 2D image frame is a function of the degree to which the respective components of polarization are delayed relative to each other and varies with wavelength variations in the output of the wavelength-tunable laser diode. Polarization variations of the frequency-converted laser beam in the 2D image frame are sufficient to scramble image speckle patterns across the 2D image frame.
