Structure of angular rate sensor

An apparatus synthesizes the image of a viewer and a second image into a synthesized image and displays the synthesized image. The apparatus is capable of aligning the line of sight of the viewer with the line of sight of the displayed image of the viewer and correctly reproducing colors on the synthesized image. The apparatus has a transparent hologram screen (15) on which a diffuser is recorded, a camera (25) for imaging a viewer (81) through the hologram screen, a synthesizer (28) for synthesizing the image of the viewer and a second image into a synthesized image, and a projector (11) for projecting signal light (31) containing the synthesized image onto the hologram screen. In place of the synthesizer, a display unit may be arranged behind the viewer. The hologram screen (15) may be combined with a mirror or a half-mirror.

Apparatus for synthesizing and displaying images

An angular velocity detector includes vibrator made of piezoelectric material and having a pair of arms. A pair of driving electrodes are attached to the arms in order to generate vibrations in the arms. A pair of detecting electrodes, which are attached to the arms, detect the vibrations of the arms. Therefore, the pair of driving electrodes can cause the arms to vibrate uniformly and stably, so that a S/N ratio of the angular velocity sensor can be improved.
