Abstract
An optical guide has at least two diffraction gratings in serial in front of a light source in order to diffract a light beam from the light source twice. The first diffraction grating could split the light beam into several parallel light beams along a first axis, and the second diffraction grating could split the light beams into several points of light along a second axis, and so on and so forth. By rotating the diffraction gratings relative to one another and by adjusting the distance between the diffraction gratings, a user of the optical guide could adjust the angle of the axis points and adjust a relative distance of the points of light relative to one another. These light beams could provide convenient guides for users in a variety of applications.
