Title:
直線状発光体の放射を対称化する装置、当該装置のアレイ、及び当該装置の応用
Document Type and Number:
Japanese Patent JP4603750
Kind Code:
B2
Abstract:
A device is proposed to symmetrize the radiation from one or from several linear optical emitters. The device possesses per emitter 1, 1a, 1b a cylindrical lens optical unit 2, 2a, 2b with one or more cylindrical lenses, which collimate each light beam in the y-direction, where by rotating at least one of the cylindrical lenses around the z-axis or by providing a discontinuous diffracting element, each light beam is diffracted at a different diffraction angle in the y-direction. The device additionally contains a director-collimator optical unit 3, which collimates each light beam in the x-direction and diffracts at different diffraction angles so that the main beams of the individual light beams in the x-direction converge at a specified distance from the emitter and run parallel in the y-direction. Finally, the device has a redirecting optical unit 4 which compensates for the diffraction of the light beam in the x-direction caused by the director-collimator optical unit 3.
