During this webinar we will cover Phasics applications in material sciences. We will show how Phasics wavefront sensing technology can be applied, in particular to perform refractive index mapping in transparent materials. Being able to precisely control the refractive index distribution in material is critical for optimal waveguides and metasurfaces design and finds a lot of applications in AR/VR, optical communications and defense industries. We will show examples and measure few samples live.
