Abstract

After a short survey, features of conical lenses solving the design problems of laser micro radars for ophthalmology are analyzed, particularly, in laser radars based on ray tracing principles. Adding the function of triangulation, new information about the eye structures can be acquired. Configurations are proposed for triangulation control in 3D space, either simultaneously for all beams, or sequentially in time, one-by-one. The beam dispatching is provided by acousto-optical deflector. Another task, easily resolvable with axicon, is protecting the retina during laser-assisted measurements of the corneal parameters. Beam path patterns are analyzed for each of the proposed applications.
