Title:
1次元照明装置及び画像生成装置
Document Type and Number:
Japanese Patent JP4478670
Kind Code:
B2
Abstract:
A one-dimensional illumination apparatus (10) includes: a light source (1) including a plurality of laser devices arrayed one-dimensionally; a wavefront dividing unit (21) including one or more cylindrical lens arrays (4a, 4b) for dividing a wavefront of light emitted from the light source (1) and superimposing divided wavefronts; a waveform superimposing unit (22) for introducing light from the wavefront dividing unit (21) to an object and superimposing divided wazfefrcnts; and a polarization converting unit (5) for rotating a plane of polarization of one lase beam of a pair of adjacent laser beams divided by the wavefront dividing unit (21). The polarization converting unit (5) is located right in front of or right behind an optical element through which laser light from the light source (1) finally passes in the wavefront dividing unit.
