A fourier transform spectrometer generic scan mechanism controller (GSMC) : Improves instrument utility and flexibility for a variety of applications

Advance of digital electronic technology into the signal processing domain facilitates significant advancement in the ability to control the scanning mechanisms of Fourier Transform Spectrometers (FTS). A generic digital controller for FTS has been developed and is now being offered as a commercial product to upgrade most commercially available FTS that use a He-Ne laser as their metrology system. This controller replaces the conventional analog signal from the laser fringes with a digital signal using a dedicated DSP and creates a more precise feedback control of the FTS scan mechanism.
