    This paper introduces an optical device which can detect not the distant object but the close object. In general, an optical camera can detect not only the close object but also the distant object. However, when we consider the tasks for the robots such as the obstacle avoidance, the object holding, the object tracking and so on, it may be desirable to detect only the close object rather than to detect all the objects. The authors, therefore, focus on the problem of the close object detection. We describe a methodology of designing a device for the close object detection and introduce a device for the close object detection. The performance of the device is also demonstrated through some experiments.
