ABSTRACT:
A monitor display unit having a hologram dry plate, formed by coating a glass base plate with sensitive material, and installed in an instrument panel of a vehicle. On the hologram dry plate are multiply recorded light interference fringes of three-dimensional images of the vehicle seen from the front and the rear of the vehicle. Two image reproduction lamps for illuminating reproduction light toward the hologram dry plate are provided on the right front and the left front of the hologram dry plate. When one image reproduction lamp is lighted, one three-dimensional image is reproduced on the hologram dry plate. Light emission diodes are provided rearward of the hologram dry plate so as to correspond to the positions of lamps on the three-dimensional image. The light emission of the light emission diodes is recognized through the hologram dry plate. A control circuit operates one of the image reproduction lamps to reproduce one three-dimensional image indicating the positions of the monitored lamps and to light the light emissions diodes corresponding to the monitored lamps on the three-dimensional image.
