Optical tomographic imaging apparatus and method for controlling the same

摘要

An optical tomographic imaging apparatus includes a control unit configured to, in a case where an instruction to narrow an imaging range of a tomographic image is issued, control a measurement light optical path length changing unit to reduce an optical path length of measurement light and make a changing speed of the optical path length of the measurement light lower than in a case where an instruction to widen the imaging range is issued.

主权项

1. An optical tomographic imaging apparatus configured to obtain a tomographic image of an anterior eye based on light into which return light from the anterior eye 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 input an instruction on a size of an imaging range of the tomographic image; and a control unit configured to, in a case where an instruction to narrow the imaging range is input, control the measurement light optical path length changing unit to reduce the optical path length of the measurement light and make a changing speed of the optical path length of the measurement light lower than in a case where an instruction to widen the imaging range is input.
