Abstract
Methods and systems for automatically adjusting a sample position in a spectrometer, such as a Fourier-transform infrared (FTIR) spectrometer, are described. The sample may be automatically positioned using an auto-focusing procedure. For example, images including an aperture marker are acquired by directing light towards the sample via an aperture. The sample position may be adjusted based on features extracted from the aperture marker images.
