Sammendrag
Abstract: We have designed a FTIR instrument where the traditional He-Ne reference laser is replaced by a low-cost linear encoder. We achieve an RMS sampling error of less than 50nm by oversampling both the interferogram and the encoder signal and then resampling the interferogram using a correction table for the encoder.OCIS codes: (300.0300) Spectroscopy; (300.6300) Spectroscopy, Fourier transforms; (300.6340) Spectroscopy, infrared
