Laser transformer lens
First Claim
1. A device configured to transform an impinging laser beam into a laser sheet, the device comprising:
- a lens having a solid portion and a cavity, a shape of the lens being defined by an exterior wall and a shape of the cavity being defined by an interior wall, and the solid portion being bounded by the interior wall and the exterior wall,wherein the lens is configured to transform the impinging laser beam into the laser sheet at a subtended angle of at least greater than 180 degrees wherein a distance between a source of the impinging light and the lens, and a distance between the lens and a surface on which the laser sheet is projected, are each less a distance between a center of the projected laser sheet and an edge of the projected laser sheet.

Abstract
The laser transformer lens is a hollow shaped translucent lens that transforms a laser beam into a laser sheet substantially which is capable of spanning a planar space nearly. In the event that the optical characteristics of the laser beam and the laser transformer lens are designed properly, a laser sheet of controlled form may be developed as the laser light enters, traverses, and exits the lens. The projection of the transmitted laser sheet, as it impinges on an opaque surface remote from the laser transformer lens results in a laser curve along the surface area which the laser sheet strikes. Moreover, hybrid designs of the laser transformer lens may tune substantially the waveform characteristics such as: wave speed, phase velocity, group velocity, reflection, transmission, refraction, amplitude modulation, frequency modulation, attenuation, fan angle, and wave width.
