Abstract
An ophthalmic device that may include: a light source; a measurement optical system that generates measurement light; a first reference optical system that generates first reference light; a second reference optical system that generates second reference light; and an interference optical system that generates measurement interference light from the measurement light and the first reference light, and reference interference light from the first and second reference light. The measurement optical system may include a switching unit that switches between a first state in which the subject eye is irradiated with the light from the light source and a second state in which the light from the light source is guided to the second reference optical system branching from the measurement optical system. The controller may control the switching unit to detect the measurement interference light in the first state, and the reference interference light in the second state.
