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： An object of the present invention is to provide a detection device which does not cause the false detection by receiving laser light from an oncoming car.The pulse laser light modulated with a modulation pattern set every target position is irradiated at the target position from a laser irradiation portion. DSP (Digital Signal Processor) decides that there is an obstacle at the target position only when the modulation pattern of the pulse laser light emitted from the laser emitting portion matches with the modulation pattern of the pulse laser light received by the laser receiving portion. It is suppressed that the detection device misdetects the conditions of the target position when receiving laser light from an oncoming car or the like because modulation pattern of laser light from own does not match with modulation pattern of laser light from the oncoming car or the like.

摘要： A DSP control circuit monitors a scan position of laser beams on the target region based on a signal from a PSD. Further, the DSP control circuit measures an amount of laser beams reflected from the target region for each scan position based on a signal from a beam receiving portion. The DSP control circuit compares an amount of reflected beams P0 at a scan position (reference position) on the target region with an amount of reflected beams Pk at a scan position adjacent to the scan position. If Pk/P0 is equal to or smaller than a threshold value Rs, it is determined that the scan position corresponding to the amount of reflected beams Pk is nonuniform in irradiation intensity of the laser beams. The DSP control circuit increases emission intensity plurality of times for the position that is determined to be nonuniform in irradiation intensity of the laser beams. With this, it is possible to make irradiation intensityies of the laser beams uniform over the target region.

摘要： A composite growth-assisting substrate 10 is formed by epitaxially growing a separation-assisting compound semiconductor layer 10k composed of a non-GaAs III-V compound semiconductor single crystal, and then a sub-substrate 10e composed of a GaAs single crystal in this order, on a first main surface of a substrate bulk 10m composed of a GaAs single crystal. The sub-substrate portion 10e is then separated from the composite growth-assisting substrate 10, so as to be left as a residual substrate portion 1 on a second main surface of the main compound semiconductor layer 40, and a portion of the residual substrate portion 1 is cut off to thereby form a cut-off portion 1j having a bottom surface used as a light extraction surface. By this configuration, the light emitting device is provided as allowing effective use of the GaAs substrate, and increasing the light extraction efficiency.

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.
