摘要： A semiconductor laser gyro including a photodetector and a semiconductor laser 10 that emits first and second laser lights. The photodetector is disposed in a position where interference fringes are formed by the first and second laser lights. The semiconductor laser 10 includes an active layer as well as first and second electrodes 13 and 14 for injecting carriers into the active layer. The first laser light is one obtained through emission of a part of laser light (L1) that circulates on a polygonal path in the active layer. The second laser light is one obtained through emission of a part of laser light (L2) that circulates on the polygonal path in the opposite direction to the laser light (L1).

摘要： Horizontal vibration shakers 21a and 21b are disposed opposite to each other on both sides of a vibration table 4, and either of the horizontal vibration shakers, e.g. 21a is arranged vertically movable so as to produce a positional difference (offset) with respect to a horizontal vibration axis 63 of the other horizontal vibration shaker 21b. When it is supposed that an accelerated velocity appears upwards on the left side of the vibration table 4, while another accelerated velocity appears downwards on the right side of the vibration table 4 as a result of generation of a rotational mode M, one of the horizontal vibration shakers, e.g. 21a, is elevated to produce the positional difference (offset) with respect to the horizontal vibration axis 63 of the other opposed horizontal vibration shaker 21b. In addition, vibration forces of the horizontal vibration shakers 21a and 21b are controlled at the same time to produce a moment towards the reverse direction, whereby the rotational mode M is suppressed so as to balance the right and left moments.

摘要： A photo isolator transmits light of a frequency fo in the normal direction and substantially intercepts the light in the reverse direction. A phase modulator comprising an optical crystal having a refractive index, counter faces and counter electrodes formed on the counter faces. The phase modulator receives an electrical signal having a frequency of .DELTA.f or higher and changes the refractive index of the optical crystal by the Pockels effect. A narrow band pass filter has a half band width of .DELTA.f, is mounted on an optical axis, and substantially transmits light having frequency of from (fo-.DELTA.f) to (fo+.DELTA.f). The phase modulator is juxtaposed with the narrow band pass filter on the optical axis.
