摘要： A light refracting element formed in parallel plate shape is attached to a support shaft of a mirror holder, a semiconductor laser and a PSD are disposed at positions between which the light refracting element is sandwiched. The light refracting element is rotated by rotation of the mirror holder, and whereby a laser beam irradiation position is changed on a light acceptance surface of PSD. The laser beam irradiation position on a light acceptance surface corresponds to the mirror rotation position, so that the mirror rotation position and a laser beam scanning position in a target area can be detected based on an output from the PSD.

摘要： A beam irradiation device is provided with a laser light source which emits laser light, a mirror actuator which causes the laser light to scan a targeted area, and an emission window through which laser light reflected on a mirror of the mirror actuator is transmitted. The emission window is formed with an anti-reflection film for suppressing surface reflection. The anti-reflection film has an angle dependence such that a lower limit of a reflectance is maintained in an incident angle range (0 to 20°) of the laser light at least corresponding to a scanning range of the laser light.

摘要： In a beam irradiation device of the present invention, laser beams emitted from a semiconductor laser impinge on an irradiation lens supported by a lens actuator. The laser beams that have passed through the irradiation lens change in outgoing angle in the direction of a y-z plane as the lens actuator is driven. A laser beam scan in the target region is thus performed. A part of the laser beams that have passed through the irradiation lens is reflected and separated by a beam splitter. The separated beams are converged on a PSD through a converging lens. A DSP control circuit monitors a scan position of the laser beams that have passed through the irradiation lens based on a signal from the PSD. When an irradiation position has deviated from a scan trajectory, the DSP control circuit controls an actuator driving circuit to draw the irradiation position back onto the scan trajectory. This beam irradiation device can realize a smooth and stable beam scan operation with a simple construction.

摘要： A beam irradiation apparatus includes a light source which outputs a laser beam, a convergent lens into which the laser beam output from the light source is entered, and a scanning portion which makes the laser beam transmitted through the convergent lens scan on a target region. In the beam irradiation apparatus, the laser light source is arranged such that a pn junction surface of a laser chip is parallel with the vertical direction. Further, length of the laser beam in the vertical direction on the target region is set by length of a light emitting portion of the laser light source in the vertical direction.
