In an angle detecting apparatus and projector using range finders, range finding calculations are performed in plural directions using line type passive range finders as a range finding portion. Thus, if one range finding result is an abnormal value, the e...

A driving support system for enabling a driver to appropriately confirm environmental conditions of a moving body is provided. A plurality of imaging means for taking an image of the rear of the moving body is installed on the moving body. The plurality of...

Light emitter comprises a number of partial light sources (3a-3d) that generate partial beams (5a-5d) that are collected by collecting optics (2) and guided to the aperture of a collimator (1). The collecting optics (2) has two half-reflecting plates (12a,...

The distance sensor uses triangulation of the light from two sources (3,5) of different beam diameter after reflection from the object (8) onto a CCD array (11).
