TUNABLE FABRY-PEROT INTERFEROMETER Russian patent published in 2014 - IPC G01B9/02 G02B5/28 G01J3/26 

FIELD: physics.

SUBSTANCE: interferometer has a housing in form of two flanges placed perpendicular to the optical axis with axial through-openings, and a two-mirror resonator placed in the openings of the flanges, each mirror being mounted on the corresponding flange by a piezoelectric element. The flanges are connected to each other by a fastening assembly. Leads of the piezoelectric element are connected to the input of a control unit and the output of a generator. The output of the control unit is connected to the control input of the generator. The mirrors are attached to the end faces of the piezoelectric elements such that a plane-parallel plate can be placed between peripheral areas of the mirrors which do not participate in multiple reflection of light, the width of said plate lying in the range of variation of the gap between the mirrors, provided by the working stroke of the piezoelectric elements.

EFFECT: easy manufacture and adjustment of the interferometer, providing stability and functional flexibility in automated systems.
