Abstract
An optical module includes an actuator that includes a movable part to be moved along a predetermined direction; a first interference optical system that includes a first movable mirror, a first stationary mirror, and a first beam splitter; and a second interference optical system that includes a second movable mirror, a second stationary mirror, and a second beam splitter. The first interference optical system is adapted so that first light reciprocates m times (m is a natural number) between the first beam splitter and the first movable mirror along the predetermined direction. The second interference optical system is adapted so that second light reciprocates n times (n is a natural number greater than m) between the second beam splitter and the second movable mirror along the predetermined direction.
