    • PROBLEM TO BE SOLVED: To provide a beam irradiation apparatus capable of irradiating a target area with a beam of desired shape without using a beam-forming lens such as a cylindrical lens.
      SOLUTION: A beam irradiation apparatus includes a laser light source 410 to emit a laser light, a convergent lens 430 into which the laser light emitted by the laser light source 410 is incident, and a mirror actuator 100 for scanning a target area with the laser light transmitted through the convergent lens 430. The laser light source 410 is disposed so that a pn junction surface of a laser chip is parallel to a vertical direction. A vertical directional length of the laser light at a target area is set up by a directional length parallel to the vertical direction of a light-emitting section on the laser light source 410.

    • PROBLEM TO BE SOLVED: To provide an inexpensive and small-sized light angle detection device having high detection sensitivity.
      SOLUTION: A direction of a light source 13 can be determined based on each light reception output from first and second light receiving elements 1, 4. Since incident light 14 is condensed by first and second light receiving lenses 2, 5 and is allowed to enter the first and second light receiving elements 1, 4, even if the incident light from the light source 13 is diffused light, the light receiving amount by the first and second light receiving elements 1, 4 is not reduced remarkably, and the light reception output from the first and second light receiving elements 1, 4 which is necessary and sufficient for signal processing can be acquired, and even the direction of a distant light source 13 can be detected accurately. Further, cost is not heightened because only the two first and second light receiving elements 1, 4 are used.

    • 要解决的问题:提供具有高检测灵敏度的便宜且小型的光角度检测装置。 解决方案:可以基于来自第一和第二光接收元件1,4的每个光接收输出来确定光源13的方向。由于入射光14被第一和第二光接收透镜2,5聚光,并且是 允许进入第一和第二光接收元件1,4,即使来自光源13的入射光是漫射光,第一和第二光接收元件1,4的光接收量也不会显着降低,并且 可以获取从信号处理所必需的第一和第二光接收元件1,4输出的光接收,甚至能够准确地检测远方光源13的方向。 此外,由于仅使用两个第一和第二光接收元件1,4,所以成本不会提高。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a radar apparatus of a small-scale constitution for vehicle capable of parallelly processing the integration of light reception signals from a plurality of light reception elements.
      SOLUTION: The radar apparatus for vehicle is provided with a zero-cross comparator 95 for outputting comparison signals indicating two different states for every channel as a configuration to replace a conventional A/D conversion circuit and an integration part 77 for integrating one-bit digital data for every channel as a configuration to replace a conventional integration circuit. When an eight-bit A/D conversion circuit is, for example, in use, eight signal conductors have been required for one channel before, but here a configuration of one signal conductor for one channel is thereby sufficient. Since the integration part 77 integrates one-bit digital data, it can be replaced with a counter. It is therefore possible to parallelly process the integration of light reception signals for every channel by a small-scale circuit configuration.

    • 解决的问题:提供一种能够并行处理来自多个光接收元件的光接收信号的集成的车辆的小型构造的雷达装置。 解决方案:用于车辆的雷达装置设置有用于输出表示每个通道的两种不同状态的比较信号作为替代常规A / D转换电路的配置的零交叉比较器95和用于集成一个 的每个通道的数字数据作为替代常规集成电路的配置。 例如,当使用8位A / D转换电路时,在一个通道之前已经需要八个信号导体,但是这样一个通道的一个信号导体的配置就足够了。 由于积分部分77集成了一位数字数据,所以可以用计数器代替。 因此,可以通过小规模电路配置并行处理每个通道的光接收信号的集成。 版权所有(C)2006,JPO&NCIPI
