KUSHCHENKO'S INTERFEROMETER Russian patent published in 2017 - IPC G01B9/02 

FIELD: lighting.

SUBSTANCE: interferometer includes a coherent light source 1, a radiating original beam 2 passing through a translucent reflective plate 3 and splitting into a transmitted beam 4, and a reflected beam 5 that passes the light guide 6 and the light path with a variable path length 7 with a translucent filler 8 with a predetermined refractive index, which is provided with a length-change drive 9. The light guide 7 is connected to the light guide 10. The light unit 11 consists of the elements 6-10 and the drive 12, which makes it possible to make turns. The beam 13 emerging from the light guide 10 passes to the second semitransparent plate 14, becoming a beam 16. Also through the plate 14 the beam 4 passes, becoming a passing ray 15. The beams 15 and 16 pass through the focusing system 17 to the translucent screen 18, behind which there is a camera 19 connected to the controller 20. The controller 20 is connected to the drives 9 and 12, and also to the control panel 21, the screen 22, the modem 23.

EFFECT: increasing compactness, flexibility of adjustment.
