Multi-direction distance measuring method and apparatus

摘要

A multi-direction distance measuring method including the steps of directing a light beam to an object to be measured and scanning the same, condensing the reflected light beam reflected by the object to be measured, disposing a sensor at a position at which the reflected light beam is condensed and receiving the reflected light beam by the sensor, and determining the distance to the object to be measured on the basis of the position of incidence of the reflected light beam on the light-receiving surface of the sensor. An apparatus utilizing such a method is also provided.
