摘要： The control circuit controls the directional coupling type optical switch, inputs the excited light from the excitation LD light source mainly via the WDM coupler to the EDF, and thereby intensifies forward excitation and controls the drive current of the light source so that the signal light with a desired value is output. On the other hand, when the signal light power with a desired value is not obtained even if the drive current of the light source reaches an upper limit, the control circuit gradually increases the ratio of the excited light to be entered to the EDF via the WDM coupler and at the same time controls the drive current of the light source so that the signal light with the desired value is output.

摘要： An ophthalmic measurement apparatus comprises a laser beam projection section for projecting into an eye a linearly polarized laser light beam emitted by a laser source, and a light receiving section provided with a photosensor for detecting laser light scattering from within the eye. An angle of the optical axes formed by both the sections with respect to the eye is set to be substantially ninety degrees. The polarization direction of the laser beam from the laser beam projection section is made variable in such a way that, during alignment, the polarization direction is set substantially perpendicular to a plane that includes the optical axes of both the sections, and during measurement it is set in a direction that is substantially in the plane. This arrangement makes it possible to cut noise components caused by light scattered by flares which are much smaller than the wavelength of the light.
