Abstract
An optical tomographic imaging apparatus includes an instruction unit configured to issue an instruction on a size of an imaging range of a tomographic image, and a control unit configured to control a measurement light optical path length changing unit to perform alignment in a depth direction with respect an object after the instruction by the instruction unit, and change an optical path length of measurement light by a distance corresponding to a change of the size on which the instruction is issued.
Claims18
An optical tomographic imaging apparatus configured to obtain a tomographic image of an object based on light into which return light from the object irradiated with measurement light and reference light corresponding to the measurement light are combined, the optical tomographic imaging apparatus comprising:
- a measurement light optical path length changing unit configured to change an optical path length of the measurement light;
- an instruction unit configured to issue an instruction on a size of an imaging range of the tomographic image;
- and
- a control unit configured to control the measurement light optical path length changing unit to perform alignment in a depth direction with respect to the object after the instruction by the instruction unit, and change the optical path length of the measurement light by a distance corresponding to a change of the size on which the instruction is issued.
