Frédéric Zamkotsianing case of microemulsions using non-ionic surfactants, such as alkyloligoethylene oxides, can form phases simultaneously bicontinuous in oil and water. Fluorescence analysis provides both sensitivity and selectivity to monitor these systems. We have used pyrene and rhodamine 6G as probes to enrich

INTERFERENCES,d consequently instrumentation. It is obvious in interferometry. Grating spectroscopy is explained within the same framework as Young experiment, and Fabry–Perot filters are explained as Michelson interferometers. Polarization interferences, used in Lyot filters, are discussed, emphasizing the analo

SEGMENTED MIRROR TELESCOPES,es. The history of segmented mirror telescopes is brie.y reviewed. Segmentation geometries that might be suitable are reviewed with their advantages and disadvantages. A key issue, the asphericity of individual segments is reviewed and its impact outlined. Diffraction effects of segments are summari

,HECTOMETRIC OPTICAL TELESCOPES ESO’S 100-M OWL TELESCOPE CONCEPT,lowed the path of technology development, and even promoted it more than once. Traditional design approaches, and above all technology limitations, have limited gains in size to a mere factor 2 between successive generations. We argue that such limitations have recently shifted from the realm of poo

OPTICAL AND INFRARED DETECTORS FOR ASTRONOMY,ect, the telescope-instrument act as “spectacles”. The detectors, meanwhile, have the critical role of sensing the light – the detectors are the “eyes” of an observatory. The performance of an astronomical observatory is directly dependent upon the performance of its detector systems.
