Abstract
An optical device includes a tunable laser for repeatedly irradiating a sample with laser light as wavelength scans over a defined wavelength range, a trigger unit and a data acquisition unit. The laser outputs at least a first trigger signal and a second trigger signal. The first trigger signal outputs a temporal start and a temporal end of a wavelength scan, and the second trigger signal comprises a pattern of scanning pulses distributed over the tunable wavelength range at predefined wavelength intervals. The trigger unit has an adder which adds the trigger signals and a mixer which mixes the trigger signals with the reference signal to form the trigger output signal. A method for capturing infrared absorption spectra is also provided.
