Claim 8:
9. A computer-readable non-transitory recording medium that stores a program, the program causing a computer to execute processing, the computer being mounted on an optical coherence tomographic imager comprising:
a wavelength-tunable light source whose output light wavelength is determined by a plurality of light source drive parameters;
a splitter that branches output light of the wavelength-tunable light source into object light and reference light;
an irradiation optical system that irradiates an object to be measured with the object light;
a two-input balanced light receiver that obtains interference light intensity measurement values by causing object light scattered from the object to be measured and the reference light to interfere with each other and to be guided to a light receiver;
wherein the computer comprises:
at least a processor; and
a memory in circuit communication with the processor;

wherein the program causes the processor to reorder the interference light intensity measurement values based on the output light wavelengths; and
wherein the memory stores a corresponding relationship between light source drive parameters and optical source output light wavelength setting values for the wavelength-tunable light source; and
wherein the program causes the processor to:
obtain the interference light intensity measurement values;
generate
a first corresponding relationship between (W) the optical source output light wavelength setting values and (I) the interference light intensity measurement values from
a second corresponding relationship between (W) the optical source output light wavelength setting values and (T) a time at which they are sent from the memory, the second corresponding relationship being not a monotonic change, and
a third corresponding relationship between (T) a time and (I) the interference light intensity measurement values; and

reorder the interference light intensity measurement values in an ascending order or a descending order of the optical source output light wavelength setting values.
