PURPOSE: An optical tomography image pickup device and a control method thereof are provided to determine the formation of space variation between position relations of an image by obtaining a first eye-ground image and a second eye-ground image at different time point. CONSTITUTION: A light source(101) uses a super-luminescent diode light source or an amplified spontaneous emission light source. Low coherent light is formed in a fiber coupler(102). Metering light is discharged as the type of collimated light through fiber. The metering light passes through an OCT(Optical Coherence Tomography) scanner 105, release lenses, an OCT scanner 108, and a dichroic beam splitter. The metering light is entered in eyes to be tested by passing a scan lens, a dichroinc mirror, and an ocular. The metering light returns in the fiber coupler. Reference light is reflected by a reference mirror.
