Infrared interferometry is of interest to test IR transmitting materials. Also, the aspheric departure from the best-fit reference sphere (in terms of the source wavelength) is reduced, long-wavelength interferometry is useful in obtaining interferograms of deep aspherics with diffractive structures The principle of this diffractive interferometer is based on the phase information encoded by the ±1st order beams diffracted by a holographic grating. Properly interfering these two beams leads to modulation similar to a Doppler frequency shift that can be translated to displacement measurements via phase decoding Quadriwave lateral shearing interferometry (QWLSI principle) Quadriwave lateral shearing interferometry measures the phase and intensity of a beam with nanometric sensitivity and very high spatial resolution. This innovative technology relies on a diffractive grating that replicates the incident beam into 4 identical waves Smart solutions to fight COVID-19.
