An interferometer comprises a beam split- ter (BS) and two scanning mirrors (Ml, M2), which are parallel and disposed on a common slide member that can be linearly displaced. The interferometer further comprises two compensat- ing mirrors (M3, M4), which are disposed be- tween the beam splitter (BS) and the scanning mirrors (M1, M2). The beam splitter (BS) and each of the compensating mirrors (M3, M4) are orthogonal. The interferometer has good toler- ance for displacement inaccuracies of the scan- ning mirrors (Ml, M2). The interferometer may be used for producing a compact and inexpensive < See formula 1 > Fourier transform spectrometer.
Interféromètre comprenant un diviseur de faisceaux (BS) et deux miroirs de balayage (M1, M2) parallèles et disposés sur un élément coulissant commun pouvant se déplacer de manière linéaire. L'interféromètre comporte en outre deux miroirs compensateurs (M3, M4) placés entre le diviseur de faisceaux (BS) et les miroirs de balayage (M1, M2). Le diviseur de faisceaux (BS) et chacun des miroirs compensateurs (M3, M4) sont orthogonaux. L'interféromètre présente une bonne tolérance aux imprécisions de déplacement des miroirs de balayage (M1, M2). Il peut être utilisé pour obtenir un spectromètre de transformée de Fourier compacte et peu coûteux.
