摘要： A scanning optical device that includes a light source that emits a light flux; a polygon mirror for deflecting the light flux; a scanning lens for converging the light flux deflected by the polygon mirror to form a beam spot on an image surface; a dynamic prism that is rotatably disposed between the light source and the polygon mirror to affect the direction of the light flux; a driving mechanism for rotating the dynamic prism to change the deviation angle of the dynamic prism; and a controller for controlling the driving mechanism to change the position of the beam spot during scanning. In particular, the controller rotates the dynamic prism to compensate for errors that affect the position of the beam spot on the image surface, such as errors that vary with time and errors that occur randomly during the scanning process.

摘要： An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.

摘要： A light transmission device includes a semiconductor laser for emitting a laser flux, an optical fiber for transmitting the laser flux emitted from the semiconductor laser, and a device that prevents the laser flux, reflected at an incident end surface of the optical fiber, from returning to the semiconductor laser. In particular, the preventing device may be a slanted incident end surface of the optical fiber, such that the reflected laser flux at the incident end surface is directed away from the semiconductor laser. The preventing device may also be an optical isolator that is disposed between the semiconductor laser and the incident end surface of the optical fiber.

摘要： A light intensity controlling device has a beam splitter which splits light fluxes emitted from a plurality of independently controlled semiconductor lasers, guided by optical fibers, into monitor light fluxes and main light fluxes. A gain adjusting circuit corrects the changes of output of light receiving elements depending on the polarization states of the light fluxes incident into the beam splitter. The changes result from the polarization characteristics of the optical fibers and/or the beam splitter. Alternatively, a filter is provided at one of the light receiving elements to compensate for the changes, thus providing a corrected output signal. Laser control circuits control the light emitting intensity of each semiconductor laser based on corrected output signals. The light receiving elements are set at an angle to the incoming light as so to avoid directing reflected light back toward an imaging system or the lasers.
