1. A camera comprising:
a first optical structure configured to refract and reflect a first beam input from a first direction to output a second beam to a second direction with a width smaller than a width of the first beam; and
a second optical structure configured to refract and reflect the second beam from the first optical structure to output a third beam to the first direction with a width greater than the width of the second beam,
wherein a height of the first optical structure and a height of the second optical structure are the same,
wherein a width of the first beam and a width of the third beam are the same,
wherein the first optical structure comprises a first reflection surface configured to reflect the first beam, and
wherein a first angle between an orthogonal surface orthogonal to the first beam and the first reflection surface is greater than 0° and smaller than 45°.
