PROBLEM TO BE SOLVED: To provide an optical interference tomographic image generation device capable of easily adjusting an optical path length.SOLUTION: An optical interference tomographic image generation device (1) includes: a collimator 19d which converges reference light into parallel light; a reference light condenser lens 20 which condenses the parallel light converged by the collimator 19d on a reference mirror 21; and optical path length changing means 24 which changes the optical path length from a light divider (12) to the reference mirror 21 by moving the collimator 19d in an optical axis direction. The optical path length changing means 24 includes: an optical path length adjustment actuator M which changes the optical path length from the light divider (12) to the reference mirror 21 by moving the collimator 19d in the optical axis direction; and an actuator control part 55 which drives the optical path length adjustment actuator M. |
