A good article explains how the 200 nm resolution of an optical microscopy comes from.[PDF]
Princeton Optronics is the technology leader in high power VCSEL diode laser technology and in the area of diode laser pumped low noise laser technology. The technology section write-up is organized as follows: HIGH RESOLUTION WAVEFRONT ANALYSIS
ONERA* patented technology Phasics wavefront sensors all rely on an innovative patented technology: the quadriwave lateral shearing interferometry (QWLSI). It is based on a modified Hartmann mask to measure wavefront distortions. Xtion PRO developer solution to make motion-sensing applications and games
Here is some useful information about FFT Zero Padding
An excellent account of the theory and experimental processes of optically induced acoustic waves in liquids and gases can be found in Sigrist:
