1. An optical apparatus comprising:
an illumination unit which is configured to emit a first ray having a first wavelength and a second ray having a second wavelength different from the first wavelength to an object;
an imaging unit including a first pixel which is configured to receive the first ray emitted to the object and a second pixel which is configured to receive the second ray emitted to the object, the imaging unit being configured to capture an image based on the first ray received by the first pixel and the second ray received by the second pixel; and
a processor which is configured to calculate a first ray direction of the first ray and a second ray direction of the second ray based on the image captured by the imaging unit,
wherein the processor is configured to:
cause the imaging unit to capture a first image based on the first ray received by the first pixel; and
causes the imaging unit to capture a second image based on the second ray received by the second pixel.
