Title (EN) SPECKLE REDUCTION DEVICE, LASER LIGHT SOURCE, AND LASER PROJECTION SYSTEM
(FR) DISPOSITIF DE RÉDUCTION DE GRANULARITÉ, SOURCE DE LUMIÈRE LASER ET SYSTÈME DE PROJECTION LASER
(ZH) 消散斑装置、激光光源及激光投影系统
Abstract:
(EN) A speckle reduction device, a laser light source, and a laser projection system. The speckle reduction device comprises: a waveplate (100) located on an optical path of a laser. The waveplate (100) is arranged such that 25-75% of the laser beam directly passes therethrough. The invention reduces speckling effects of a laser.
(FR) L'invention concerne un dispositif de réduction de granularité, une source de lumière laser et un système de projection laser. Le dispositif de réduction de granularité comprend : une lame d'onde (100) située sur un trajet optique d'un laser. La lame d'onde (100) est agencée de telle sorte que 25 à 75 % du faisceau laser passe directement à travers celle-ci. L'invention réduit les effets de granularité d'un laser.
(ZH) 一种消散斑装置、激光光源及激光投影系统,消散斑装置包括位于激光光路的波片(100),波片(100)布置为使入射激光束的25%-75%直接通过。可消除激光散斑现象。
