Photorefractive laser beamsteering device |
摘要 |
Apparatus for steering a principal beam of electromagnetic radiation consisting of a photorefractive material situated such that the principal beam of radiation passes therethrough, the material being photoconductive and having an index of refraction that is variable in response to transverse electro-optical effects; and variable writing means for irradiating the material in a direction orthogonal to the principal beam with two beams which intersect at a variable angle so as to write a diffraction grating in the material and thereby vary the index of refraction of the material, thus steering the principal beam.
