| Zusammenfassung: | To realize a small optical deflection element that allows a high-resolution raster scan.SOLUTION: An optical deflection element (100) includes: a first optical element (an optical fiber 120 and a first lens unit 121); a vibrator (a first actuator unit 111) provided in a light entrance side end part of the first optical element to vibrate a light emission side end part of the first optical element in a first direction; and a second optical element (a second lens unit 122) for moving slower than the first optical element in a second direction different from the first direction.SELECTED DRAWING: Figure 1
【課題】高解像度なラスタースキャンが可能な小型の光偏向素子を実現すること。【解決手段】第１の光学素子（光ファイバー部１２０と第１のレンズ部１２１）と、第１の光学素子の光出射側端部を第１の方向に振動させるように第１の光学素子の光入射側端部に設けられた加振部（第１のアクチュエータ部１１１）と、第1の方向とは異なる方向である第２の方向に前記第１の光学素子よりも低速で運動する第２の光学素子（第２のレンズ部１２２）と、を備える光偏向素子（１００）とする。【選択図】図１ |
