Abstract
In a laser radar apparatus, a laser beam generator that generates a laser beam and an optical detector that detects reflected light that has been reflected by an object in a field to be observed. A deflection performing means, provided with one or more deflection means each rotatable on a given central axis thereof, for enabling the deflection means to deflect the laser beam to the field and to deflect the reflected light toward the optical detector. A drive means driven to rotate the deflection means. A direction changing means changes a direction of the laser beam from the deflection means is changed in a direction of the central axis. A control means controls an operation of the direction changing means.
