Fringe projection technique has been a powerful tool for 3D metrology and surface profilometry with high repeatability. However, for in-situ measurement of objects with highly specular surfaces, large dimensions, and large varying slopes, acquirin...
With the advent of microsphere assisted microscopy in 2011, this technique emerged as a simple and easy way to obtain optical super-resolution. Although the possible mechanisms of imaging by microspheres are debated in the literature, most of the ...
