Holographic second harmonic generation (SHG) microscopy

Christian Depeursinge, Pierre Marquet, Etienne Shaffer

The coherent nature of second harmonic generation (SHG) makes possible retrieval of both its amplitude and its phase, by use of a proper phase-sensitive imaging technique such as digital holographic SHG microscopy. In addition to retrieving both amplitude ...

Harmonic distortion factor of space vector PWM for a five-phase inverter

Drazen Dujic

Various PWM methods for multi-phase (n>3) two-level voltage source inverters (VSIs) have been developed recently. Relatively little work has however been done in relation to switching harmonic properties of these PWM methods and their impact on current rip ...
