Collimation of asymmetric laser diode at 450 nm using multimode fiber for speckle reduction through diffractive diffusers

Multi-Wavelength Speckle Reduction for Laser Pico-Projectors Using Diffractive Optics

“…The main drawback of using such a large fiber is its stiffness and thus high bend radius. Manipulation of the incident laser beam by passing through a fiber is investigated to determine whether using fiber optics for beam steering in projectors is viable [33]. Finally, an investigation into polarization manipulation and its effects on diffuser speckle contrast output is conducted and analyzed.…”
