发明名称 Image capturing apparatus, image capturing method, and storage medium
摘要 An image capturing apparatus includes a dividing unit configured to divide light from a light source into reference light and measurement light; a first dichroic mirror arranged in a measurement optical path for guiding the measurement light to an object to be examined; a second dichroic mirror arranged in a reference optical path for guiding the reference light to a reference object; and a light receiving unit configured to receive interference light between the measurement light passing through the first dichroic mirror and the reference light passing through the second dichroic mirror.

主权项 1. An image capturing apparatus comprising: a dividing unit configured to divide light from a measurement light source into reference light and measurement light; a light receiving unit configured to receive interference light between (a) return light from an object to be examined based on the measurement light and (b) the reference light; an interference signal acquisition unit configured to acquire an interference signal based on the interference light received by said light receiving unit; an interference signal correction unit configured to separate the interference signal into a signal including information representing a phase characteristic of the interference light and a signal including no information representing the phase characteristic of the interference light; and a tomographic image acquisition unit configured to acquire a tomographic image of the object by using the signal including no information representing the phase characteristic of the interference light, wherein said dividing unit comprises an optical coupler, wherein said light receiving unit comprises a line sensor, and wherein said interference signal acquisition unit, said interference signal correction unit, and said tomographic image acquisition unit are implemented using a processor.
