20110051209 | BEAM IRRADIATION APPARATUS AND LASER RADAR - 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. 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. Further, a wavefront aberration of the convergent lens with respect to the laser beam is set to be 0.15 λrms or less. | 03-03-2011 |

20110182071 | BEAM IRRADIATION DEVICE AND SEMICONDUCTOR LASER DEVICE - A beam irradiation device includes a semiconductor laser; a lens into which laser light emitted from the semiconductor laser is entered; and a scanning portion which causes the laser light transmitted through the lens to scan a targeted area. In this arrangement, the semiconductor laser has a laser chip; a cap which houses the laser chip; and an emission opening formed in the cap and adapted to pass laser light emitted from the laser chip. The emission opening has an aperture which restricts an incident area of the laser light into the lens. | 07-28-2011 |

20110298545 | RF POWER AMPLIFIER DEVICE AND OPERATING METHOD THEREOF - An RF power amplifier device includes a driver stage amplifier, a first RF amplifier, a second RF amplifier and a DC voltage converter operated by first, second and third external power supply voltages. The output of the driver stage amplifier is supplied to the inputs of the first and second RF amplifiers. An effective device size of the first RF amplifier is set to a device size larger than that of the second RF amplifier. The third external power supply voltage is supplied to the DC voltage converter, so that the DC voltage converter generates a fourth operating power supply voltage corresponding to a low voltage and supplies it to an output terminal of the second RF amplifier. An output terminal of the first RF amplifier can be supplied with the second external power supply voltage without via the DC voltage converter. | 12-08-2011 |

20120327310 | OBJECT DETECTING DEVICE AND INFORMATION ACQUIRING DEVICE - An information acquiring device has a light source which emits light of a predetermined wavelength band; a projection optical system which projects the light emitted from the light source toward the target area with a predetermined dot pattern; a light receiving element which receives reflected light reflected on the target area for outputting a signal; a storage which stores a reference template in which a plurality of reference segment areas are set on a reference pattern of the light to be received by the light receiving element; and an updating section which updates the reference template. In this arrangement, the updating section updates the reference template, based on a displacement to be detected when a referenced segment area set in the reference template is actually measured. | 12-27-2012 |
20130003069 | OBJECT DETECTING DEVICE AND INFORMATION ACQUIRING DEVICE - An information acquiring device has a laser light source which emits laser light of a predetermined wavelength band; a collimator lens which converts the laser light emitted from the laser light source into parallel light; an image sensor which receives reflected light reflected on a target area for outputting a signal; and a CPU which acquires three-dimensional information of an object in the target area based on the signal to be outputted from the image sensor. A light diffractive portion for converting the laser light into laser light having a dot pattern by diffraction is integrally formed on a light exit surface of the collimator lens. | 01-03-2013 |
20130038882 | OBJECT DETECTING DEVICE AND INFORMATION ACQUIRING DEVICE - An information acquiring device has a light source which emits light in a predetermined wavelength band; a projection optical system which projects the light toward a target area; and a light receiving element which receives reflected light reflected on the target area for outputting a signal. First signal value information relating to a value of a signal outputted from the light receiving element during a period when the light is emitted from the light source, and second signal value information relating to a value of a signal outputted from the light receiving element during a period when the light is not emitted from the light source are stored in a storage. An information acquiring section acquires three-dimensional information of an object in the target area, based on a subtraction result obtained by subtracting the second signal value information from the first signal value information stored in the storage. | 02-14-2013 |
