摘要： A laser projector includes a green laser, a two-wavelength laser, a PBS, a collimator lens, a two-axis galvanometer mirror, a group of lenses, and a screen. The green laser emits a green laser beam. The two-wavelength laser emits red and blue laser beams. The PBS is provided at the position where respective optical paths of laser beams emitted from respective lasers cross each other to cause these optical paths to coincide with each other.

摘要： An image display apparatus is provided that allows a user to check image content even in a place where there is no projection screen. A projector that is one mode of the image display apparatus includes a casing, a projection aperture provided in the casing, and an internal projection mirror and a built-in screen that are provided in a casing. When the projector is being folded, laser light emitted from the projection aperture is reflected by the internal projection mirror. The reflected light is projected onto the built-in screen, whereby an image is displayed.

摘要： A deviation of an optic axis of a laser projector is detected, and the deviation is corrected. Laser projector's CPU executes: commanding a laser beam source of one color, out of laser beam sources of three colors, to emit a laser beam; shutting off the laser when sensing that the laser beam is received in a light-receiving region; applying a laser of a color to be detected as to the presence or absence of a deviation of the axis until its reception in the light-receiving region is sensed; keeping time starting when light reception in the light-receiving region is sensed and ending when light reception in a light-receiving region adjacent thereto is sensed; calculating a relative time difference of each of the colors with respect to a reference color; and correcting a light emission timing of the laser beam source of each of the color, based on the calculated time.
