Signal-to-Signal-to-Noise-Ratio of Full-Field Fourier
... In 3F-OCT we use a holographic interferometer instead of the Michelson interferometer typically used for “flying spot” OCT configurations. Here for simplicity we describe 3F-OCT in the transmission mode (extendable to reflection mode). Our optical source is launched into a fiber-optic coupler which ...

observing sunspots using a pinhole camera
... You may be wondering, at a time when the bigger the optic, the better the observing (otherwise known as aperture fever) why study the sun using a pinhole. Some years ago (ca. 1990-91) I wanted to know what the limits of observing with the minimum of optics might be, and wondered if sunspots might be ...

Summary of accomplishments in the last year: The main objective of the project is to ensure the control of the ELI laser pulse temporally, spectrally and spatially, during its propagation, from generation to the target. The task for year 2014 was to establish a framework method that can be adapted ...
