摘要： An optical scanner for scanning light signals, such as light beams, including an electrostrictive element attached at one end thereof to a base body, a convex mirror fixed to the other end of the electrostrictive element, a driving circuit for changing a voltage applied to the electrostrictive element, and an emitter for emitting a light beam to the surface of the convex mirror in a direction different from the modified direction of the electrostrictive element. When the applied voltage to the electrostrictive element changes by the driving circuit during reflecting light beams on the convex mirror surface, the electrostrictive element is modified according to the applied voltage. Simultaneously light beams are scanned over a wide range, even if the modified volume is small, due to continuous change of deflection angles of beams according to the radius of the curvature of the convex mirror.

摘要： A laser beam with a wavelength .lambda. emitted from a laser beam source is split into first and second pump beams and a probe beam. The first and second pump beams are incident on light incident surfaces of a photo-nonlinear medium from opposing directions on the same optical path. The probe beam is incident on the light incident surface forming an angle with the first pump beam to generate interference fringes in the normal direction of the light incident surface and to form a refractive index grating. A phase conjugate wave is emitted in the reverse direction to an incident optical path of the probe beam by means of irradiating the second pump beam on the refractive index grating. A direct -current electric field is applied on a pair of external electrodes to be coincident to the wave vector of the interference fringes, where by providing a frequency modulation to the first pump beam using a piezoelectric oscillator, a moving speed "v" of the interference fringes is determined when light intensity of the phase conjugate wave is maximized. A forming time .tau. of the refractive index grating can thus be obtained. An accurate and rapid measurement can generally be obtained for the forming time of the refractive index grating of the photononlinear medium formed of photorefractive crystal including a cubic system such as BSO.
