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.

1. An image capturing apparatus comprising:
an optical coupler configured to divide light from a light source into reference light and measurement light; a first dichroic mirror arranged in a measurement optical path connecting said optical coupler and an object to be examined, and configured to guide, by reflecting the measurement light, the measurement light to the object to be examined; a reference dichroic mirror arranged in a reference optical path connecting said optical coupler and a reference object and configured to guide, by reflecting the reference light, the reference light to the reference object; and a light sensor configured to receive interference light between first return light from the object to be examined irradiated by the measurement light and reference return light from the reference object irradiated by the reference light.
