Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は光学部品に関し、特に光偏向器に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to optical components, and more particularly to optical deflectors.
従来、この種の光偏向器は回転多面鏡により構成されて
いた。Conventionally, this type of optical deflector has been composed of a rotating polygon mirror.
上述した従来の光偏向器は高周波のドライブが必要であ
ったり、鏡面や複数の鏡面相互の角度、さらに、回転軸
と鏡面との間に高い精度が要求されるため、部品１組立
工数、保守に難点があるばかりでなく、光学系が大規模
になるという欠点がある。The conventional optical deflector described above requires a high-frequency drive, a mirror surface, the mutual angle of multiple mirror surfaces, and high precision between the rotation axis and the mirror surface, so it requires less man-hours for assembly per part and maintenance. Not only does this have some drawbacks, but it also has the disadvantage of requiring a large-scale optical system.
本発明の目的は前記課題を解決した光偏向器を提供する
ことにある。An object of the present invention is to provide an optical deflector that solves the above problems.
前記目的を達成するため、本発明は光ビームの反射式偏
向器において、光学系の光路を形成する対向した一対の
鏡の組を有し、一方の鏡を固定し、他方の鏡を電歪素子
に支持させて前記一方の鏡に対し傾斜可能に配設したも
のである。To achieve the above object, the present invention provides a reflective deflector for a light beam, which has a pair of opposing mirrors forming an optical path of an optical system, one mirror is fixed, and the other mirror is electrostrictive. It is supported by an element and is arranged so as to be tiltable with respect to the one mirror.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例を示す断面図である。FIG. 1 is a sectional view showing one embodiment of the present invention.

を装備したものである。In the figure, the present invention includes a pair of mirrors 1 and 2 facing each other forming an optical path of an optical system, one mirror 1 is fixed in a fixed position, and the other ia2 is supported by an electrostrictive element 3. The bell 1 is arranged so as to be tiltable, and the electrostrictive element 3 is provided with a driver 7.
It is equipped with.
実施例において、被偏向光４は鏡１と鏡２の間で反射を
繰り返し行い、出射角６で偏向光５となる。In the embodiment, the deflected light 4 is repeatedly reflected between the mirrors 1 and 2, and becomes the deflected light 5 at an output angle of 6.
ここで、偏向光５の出射角を変化させるにあたっては第

って偏向光９が出力されることとなる。Here, in changing the output angle of the deflected light 5, the electrostrictive element 3 is distorted in proportion to the output of the driver 7, and the mirror 2 is tilted at an inclination angle 8, as shown in FIG. Opposing at an angle! By causing light to be reflected back and forth between Ji1 and mirror 2, polarized light 9 is output with an output angle 10 that is twice the inclination angle 8.
以上説明したように本発明は、向い合った鏡の間で光を

。As explained above, the present invention allows light to propagate while being reflected between mirrors facing each other, and by tilting one mirror with an electrostrictive element, the deflection angle and deflection speed can be easily controlled. In addition, by miniaturizing the optical system, it is possible to contribute to miniaturization and weight reduction of the device.
