Abstract
An optical moduleA includes a mirror unitincluding a movable mirrorand a fixed mirror, a beam splitter unit, a light incident unit, a first light detector, a second light source, a second light detector, a holding unit, a first mirror, a second mirror, and a third mirror. The holding unitholds the first light detector, the second light detector, and the second light sourceso as to face that same side, and to be aligned in this order. A length of an optical path between the unitand the detectoris shorter than a length of an optical path between the unitand the detector, and a length of an optical path between the unitand the source
