Abstract
PURPOSE:To make possible desired controlling of scanning speed with a simple constitution by generating the luminescent spot of a desired value or more in luminance from the superposed portion of the refractive index fluctuating part moving along with the ultrasonic waves propagating from both sides of the optical guide. CONSTITUTION:The refractive index fluctuating part moves in the opposite directions along the waveguide 11 according to the propagation of the ultrasonic waves generated by the ultrasonic wave transducers 10, 13 on both sides of the optical guide 11 formed by dielectric, thus according to the ultrasonic waves being propagated, the generating position of the superposed part 14 of the refractive index fluctuating part changes. On the other hand, a luminous spot of the specified value or more in luminance is generated in the superposed part 14 by the light entering from a prism 6 and propagating in the waveguide 11. Hence, if the light of this luminous spot is used for scanning light and ultrasonic waves are controlled by this, the scanning speed may be controlled as desired by the simple constitution.
