Equipment complex and method for aiming laser beams at specified target points

摘要

We describe a technique for automatic alignment and targeting of laser beams on a specific point in space using the simulated cubical targets typically used for focusing and targeting of laser light in a multiple beamline laser facility where the target is illuminated in cubical symmetry for high-temperature plasma physics research. We describe the targeting system and the steps for targeting and focusing laser beams at specific points in the target chamber, as well as a method for measuring the length of an arbitrary line segment on a distant object from an image on a display, and an experimental estimate of the accuracy of such measurements on a test object-the edge of the simulated cubical target.
