Provided are an optical coherence tomography device, imaging method, and imaging program that have position accuracy that is not easily influenced by operation conditions of a light source and the like. An optical coherence tomography device (100) comprises: a branching and merging device (103) that branches light emitted from a wavelength-sweeping laser light source (101) into object light and reference light; a balance-type light-reception device (108) that generates information about variation in the intensity ratio between interference light R(5) and R(6) produced by reference light and object light that has passed through a transparent substrate (106) having a structure with varying thickness formed on the surface thereof, been emitted onto an object (200) of measurement, and been scattered by the object (200) of measurement; and a control unit (110) that acquires structure data for the depth direction of the object (200) of measurement on the basis of the information about the variation in the interference light R(5), R(6) intensity ratio. Using the position of the structure on the transparent substrate (106) as a reference, the control unit (110) connects a plurality of items of depth-direction structure data acquired while moving the emission position of the object light R(1).
