Abstract: A technique is described for generating a Bessel beam. An input optical fiber is provided that supports propagation in the fundamental mode. The input fiber is connected to a fiber mode converting device that provides phase matching, at a predetermined excitation wavelength, between the fundamental mode and a selected azimuthally symmetric higher-order mode. As an input to the fiber mode converting device, a coherent light beam is fed through the input optical fiber to provide a fundamental mode input at the excitation wavelength. The fiber mode converting device resonantly excites the selected azimuthally symmetric mode. The azimuthally symmetric mode is provided as a beam output from an endface of the fiber mode converting device to approximate a Bessel beam.

Abstract: A primary waveguide and a coupling waveguide are arranged so a user can view light from a forward scene through the primary waveguide. An image source generates an image which is diffractively coupled into the primary waveguide and internally reflected to an exit area for diffraction towards the user. Light from the forward looking scene is diffracted into the primary waveguide to be internally reflected and coupled to a image intensifier tube assembly. The image intensifier tube assembly enhances light from the forward looking scene and drives the image source such that an image of the enhanced light is overlaid on light from a forward scene at exit area.
