Optimize the signal acquisition for optical measurements

Optical measurements are ideally suited to study smallest changes in a parameter or a signal of importance to a physical system. Capturing that underneath an inevitable noise is the crucial task for measurement schemes like lock-in amplifiers and boxcar averagers.

To minimize the implementation effort, save precious measurement time and record high-quality data, it is essential to choose the best approach and settings for a given experiment.

In this webinar you will be provided with guidelines for different experiments in optics and photonics with a focus on:

  • Tunable diode laser absorption spectroscopy (TDLAS), representing linear spectroscopy.
  • Pump-probe spectroscopy, as an example of nonlinear and ultrafast techniques.
  • Stimulated Raman scattering (SRS) microscopy, standing for all laser scanning imaging applications.
  • Carrier-envelope offset (CEO) stabilization, as an example of laser locking methods.

During this webinar you will learn how to:

  • Choose the most suitable measurement scheme, e.g. lock-in amplifier or boxcar averager.
  • Tune your measurement setting to maximize the signal-to-noise ratio.
  • Speed up the implementation of the measurement method.
