Abstract:
An optical detection device includes a light emitting element, which is an area sensor, a light emitting lens part for irradiating an object to be measured with a bundle of emission rays emitted from the light emitting element, a light receiving lens part for condensing reflected light from the object, a light receiving element for detecting reflected light from the object condensed by the light receiving lens part, and a signal processing section for processing a light-reception signal from the light receiving element. Based on the light-reception signal from the light receiving element, the signal processing section detects at least one of an x-coordinate or a y-coordinate of the object on an x-y coordinate plane from at least one of a light-spot position or a light-spot shape on the light receiving element.
