PURPOSE: A light projector using laser is provided to obtain an optimal image at night by installing an objective lens at an optimal position. CONSTITUTION: In a light projector, a zoom lens area(30) is fixed at the front on a central axis line inside a hollow case(20) and includes an eyepiece(31) and objective lens(33). A lens drive part(40) moves the objective lens, and a lens position detection part detects a location of the objective lens through the drive information of the lens drive part. A communication unit receives range information of a photographing device from a remote control center in the remote site. Location information of the objective lens corresponding to range information of the photographing device is stored in a storage as a lookup table. A comparison/ determining unit and a controller(90) compare the location information of the objective lens stored in the storage unit with the location information detected by a lens position detection based on the range information transmitted from a communication unit. |
