    • To provide an immersion object detection system capable of detecting an immersion object within a detection target area and specifying a position thereof irrespective of a short distance/long distance. A millimeter wave is irradiated to a detection area from a millimeter-wave RF unit through an antenna unit, and the reflected wave is detected. In the case that an immersion object exists in a short-distance area from a radar unit, the directly reflected waves from the immersion object is analyzed, thereby specifying the position of the immersion object, and in the case that the immersion object exists in a long-distance area from the radar unit, the position of the immersion object is specified in accordance with the position of the reflection member which cannot detect among the group of reflection members placed within the detection area.

    • [Object] A monitoring device for precisely taking out light for a monitor and having a simple structure and able to be made compact is provided. [Means for Resolution] A lens array 17 is attached to the tip face of an optical fiber array 12 holding optical fibers 14, 15 in parallel. A lens 19 is arranged in the lens array 17 so as to be opposed to the end face of each of the optical fibers 14, 15. A triangular prism 13 is arranged in front of the lens array 17. An incident-emitting face 22 of the triangular prism 13 is inclined with respect to the lens array 17. Signal light L emitted from the optical fiber 14 is converted into parallel light by the lens 19, and is incident to the triangular prism 13. After the signal light L is then totally reflected on the reflecting face 20, the signal light L is incident to a reflecting face 21. The incident angle of the signal light L incident to the reflecting face 21 is slightly smaller than a critical angle of the total reflection. The signal light L is leaked from the reflecting face 21 to the exterior by a constant ratio κ. Accordingly, the amount of the signal light L can be calculated by measuring this leak light La.
    • 提供了一种用于精确地取出监视器的光并且具有简单结构并且能够被制造成小型化的监视装置。 [分辨装置]透镜阵列17被并入保持光纤14,15的光纤阵列12的前端面。 透镜19配置在透镜阵列17中,以与光纤14,15的端面相对。 三角形棱镜13布置在透镜阵列17的前面。 三角形棱镜13的入射发射面22相对于透镜阵列17倾斜。 从光纤14发射的信号光L被透镜19转换为平行光,并入射到三角棱镜13。 在信号光L然后在反射面20上被全反射之后,信号光L入射到反射面21。 入射到反射面21的信号光L的入射角略小于全反射的临界角。 信号光L从反射面21向外部以恒定比例kappa泄漏。 因此,可以通过测量该泄漏光La来计算信号光L的量。
