Abstract:
An optical interferometer includes a branching-combining unit, a first optical system, a second optical system, and a drive unit. The branching-combining unit includes a branching surface, an incident surface, a first output surface, a combining surface, and a second output surface on an interface of a transparent member, the branching surface partially reflects incident light and outputs as first branched light, and transmits the rest of the incident light into the interior as second branched light, the combining surface partially combines the first branched light and the second branched light to be output to the outside as first combined light, and combines the rest of the first branched light and the second branched light to be propagated into the interior as second combined light, and the second output surface partially outputs the second combined light to the outside.

Claim (Index 1):
An optical interferometer comprising a branching-combining unit; a first optical system; a second optical system; and a drive unit, wherein\n the branching-combining unit includes a branching surface, an incident surface, a first output surface, a combining surface, and a second output surface on an interface between the interior and the exterior of a transparent member, the branching surface and the combining surface are provided separately, the branching surface partially reflects incident light entering from the outside and outputs as first branched light, and transmits the rest of the incident light into the interior as second branched light, the incident surface transmits the first branched light entering from the branching surface via the first optical system into the interior, the first output surface outputs the second branched light reaching from the branching surface through the interior to the outside, the combining surface partially combines the first branched light reaching from the incident surface through the interior, and the second branched light entering from the first output surface via the second optical system to be output to the outside as first combined light, and combines the rest of the first branched light and the second branched light to be propagated into the interior as second combined light, and the second output surface partially outputs the second combined light reaching from the combining surface through the interior to the outside, and the first optical system reflects is configured to reflect the first branched light output from the branching surface by a mirror, and directs direct the light to the incident surface, the second optical system reflects is configured to reflect the second branched light output from the first output surface by a mirror, and directs direct the light to the combining surface, and the drive unit is configured to move the mirror of the first optical system or the second optical system to adjust an optical path difference between the first branched light and the second branched light from the branching surface to the combining surface.
