Abstract
The present invention provides a very practical monitor for monitoring the periphery of a vehicle characterized in that: the dimension of the monitor in the vertical direction is small, so that the monitor can be incorporated into a small vehicle without putting any restrictions; and the performance and characteristic are excellent. The present invention discloses a specific mechanism to realize the monitor for monitoring the periphery of a vehicle. The present invention provides a monitor for monitoring the periphery of a vehicle comprising: a radiating means for radiating waves of light, having an optical system means for removing astigmatic difference of a light source; and an optical path changing means including a reflection mirror for reflecting a luminous flux radiated from the radiating means in a direction of the radiated light diffusing means. It is possible to change the optical path while astigmatic difference of the light source is being corrected.
