Claims (6)

1. Optischer Weglängenmodulator zur periodischen Veränderung der optischen Weglänge eines Lichtstrahls in der optischen Interferometrie, Spektrometrie, Holographie oder Tomographie, bei dem der Lichtstrahl (1) durch eine rotierende Mehr-Spiegel-Anordnung geleitet wird, dessen Drehachse (2) unter einem Winkel von x + 90° zum eintreffenden Lichtstrahl (1) geneigt ist und dessen Spiegel paarweise so angeordnet sind, dass jeweils zwei raumdiagonal gegenüber liegende Spiegelflächen parallel zueinander sind und der Lichtstrahl (1) nach passieren dieser Mehr-Spiegel- Anordnung an einem Retroreflektor (11) in sich reflektiert wird, wobei die Mehr-Spiegel-Anordnung aus mehr als zwei Spiegelpaaren besteht.1. Optical path length modulator for periodically changing the optical path length of a light beam in optical interferometry, spectrometry, holography or tomography, in which the light beam ( 1 ) is passed through a rotating multi-mirror arrangement, the axis of rotation ( 2 ) of which is at an angle of x + 90 ° is inclined to the incoming light beam ( 1 ) and the mirrors are arranged in pairs so that two mirror diagonally opposite mirror surfaces are parallel to each other and the light beam ( 1 ) passes through this multi-mirror arrangement on a retroreflector ( 11 ) is reflected in itself, the multi-mirror arrangement consisting of more than two pairs of mirrors. 2. Optischer Weglängenmodulator nach Anspruch 1, dadurch gekennzeichnet, dass die Spiegel als Flächen eines Glaskörpers (17) ausgeführt, oder auf zwei Trägerplatten (12, 13) paarweise angeordnet sind, so dass jeweils zwei raumdiagonal gegenüber liegende Spiegelflächen parallel zueinander sind.2. Optical path length modulator according to claim 1, characterized in that the mirrors are designed as surfaces of a glass body ( 17 ), or are arranged in pairs on two support plates ( 12 , 13 ), so that in each case two mirror surfaces lying diagonally opposite one another are parallel to one another. 3. Optischer Weglängenmodulator nach mindestens einem der vorgenannten Ansprüche, dadurch gekennzeichnet, dass vor dem Retroreflektor (11) zusätzlich ein Dispersionselement mit planparallelen Flächen (14) angeordnet ist.3. Optical path length modulator according to at least one of the preceding claims, characterized in that an additional dispersion element with plane-parallel surfaces ( 14 ) is arranged in front of the retroreflector ( 11 ). 4. Optischer Weglängenmodulator nach mindestens einem der vorgenannten Ansprüche, dadurch gekennzeichnet, dass das Dispersionselement mit planparallelen Flächen (14) eine flüssigkeitsgefüllte Küvette oder eine Planplatte ist. 4. Optical path length modulator according to at least one of the preceding claims, characterized in that the dispersion element with plane-parallel surfaces ( 14 ) is a liquid-filled cuvette or a flat plate. 5. Optischer Weglängenmodulator nach mindestens einem der vorgenannten Ansprüche, dadurch gekennzeichnet, dass vor dem Retroreflektor (11) zusätzlich ein prismenförmiges Dispersionselement (15 und 16) angeordnet ist.5. Optical path length modulator according to at least one of the preceding claims, characterized in that a prism-shaped dispersion element ( 15 and 16 ) is additionally arranged in front of the retroreflector ( 11 ). 6. Optischer Weglängenmodulator nach mindestens einem der vorgenannten Ansprüche, dadurch gekennzeichnet, dass das prismenförmige Dispersionselement (15 und 16) eine flüssigkeitsgefüllte prismenförmige Küvette oder ein Prisma ist.6. Optical path length modulator according to at least one of the preceding claims, characterized in that the prismatic dispersion element ( 15 and 16 ) is a liquid-filled prismatic cuvette or a prism.
