Abstract
A retinal scanning display includes: a light source part which radiates a laser beam; a scanning part which scans the radiated laser beam in two dimensional directions; a projection part which projects the scanned laser beam on a retina of a viewer; a light detection part which is arranged at a position on which the scanned laser beam is incident; and a light blocking part which blocks the scanned laser beam scanned at the timing detection time; and a control part which controls the radiation of the laser beam based on the detected timing of the laser beam by the light detection part. The control part allows the light source part to radiate the laser beam at the timing detection time with intensity which exceeds a maximum value of intensity of the laser beam radiated from the light source part at the image forming time.
