    • A vibration wave driven motor having a vibratory elastic member provided with an electro-mechanical energy conversion element, and a rail-type stator on which the elastic vibratory member is resiliently pressed by, for example, springs. When A.C. power is supplied to the electro-mechanical energy conversion element, a traveling vibration wave is generated in the elastic vibratory member so that a frictional force is produced to act between the stator and the elastic member so as to cause a relative movement between the elastic vibratory member and the stator. At least one of the sliding surface of the elastic vibratory member and the sliding surface of the stator has a smoothly curved configuration, so as to improve the durability of the motor.

    • A novel arrangement of variable-focal-length lens using an electrooptic effect is provided. A variable electric field is applied to an electrooptic crystal to produce therein a refractive index distribution having a lens action. The applied electric field is such that the intensity distribution of the lens varies along one direction in a plane normal to the direction of the light incidence but which has a uniform intensity distribution in the direction normal to this direction. A two-dimensional variable-focal-length lens is obtained by combining two such one-dimensional lenses in such manner that the two-lenses intersect each other at right angles with respect to the direction of the lens action. Also, a refractive index distribution having a two-dimensional lens action is produced to form a variable-focal-length lens when an electric field having an intensity distribution which varies within the plane normal to the direction of the incident light is applied to the electrooptic crystal.
    • 提供了使用电光效应的可变焦距透镜的新颖布置。 将可变电场施加到电光晶体以在其中产生具有透镜作用的折射率分布。 所施加的电场使得透镜的强度分布在垂直于光入射方向的平面中沿着一个方向变化,但是在与该方向垂直的方向上具有均匀的强度分布。 通过将两个这样的一维透镜组合成使得双透镜相对于透镜作用的方向成直角相交的方式获得二维可变焦距透镜。 此外,当具有在垂直于入射光的方向的平面内变化的强度分布的电场施加到电光时,产生具有二维透镜作用的折射率分布以形成可变焦距透镜 水晶。
