<p>PROBLEM TO BE SOLVED: To enable a rotation velocity of an imaging core to be increased without deteriorating resolution.SOLUTION: A tomographic imaging device acquiring a cross sectional image by generating interference light between reflection light and reference light by use of light output from a light source repeating wavelength sweep has a FIFO memory that stores interference light data to be obtained based on the interference light in plurality of lines, and destroys the oldest interference light data in accordance with writing of new interference light data. The tomographic imaging device is configured to: write interference light data obtained from the interference light in synchronization with repetition of the wavelength sweep in the FIFO memory as non-used interference light data; read the oldest non-used interference light data of pieces of interference data stored in the FIFO memory for each rotation of an imaging core at a prescribed angle; generate line data; and control a rotating velocity of the imaging core or cycle of the wavelength sweep on the basis of the number of pieces of non-used interference light data stored in the FIFO memory.</p> |
