Abstract We report the use of a simple interferometric technique which allows direct identification phase singularities in laser fields. Phase are observed families optical patterns formed via cooperative frequency mode locking continuous single longitudinal Na2 ring laser. The complements previously reported astigmatic imaging method, and is superior that it can be used to elucidate structure higher order stationary patterns.
Author Summary: Historically, the application of nuclear science to borehole logging began with detection natural radioactivity emitted by rocks and soils. This simple effective method found many applications, particularly in sedimentary, coal uranium deposits. Whilst this technique is still widely used today, industry quickly moved more sophisticated techniques that activate neutrons measure induced radiation infer characteristics material surrounding hole. Neutrons, as primary particles,...
The SIROLOG Prompt Gamma Neutron Activation Analysis probe is a spectrometric borehole logging tool developed by the CSIRO in Australia. principle of technique measurement characteristic intensity and energy gamma (γ) rays that result from nuclear interactions when fast neutrons bombard formation. emitted γ related to elemental composition rock, thus volumetric occurrence elements bulk rock mass intersected borehole, can be directly estimated. Downhole has certain benefits over conventional...
We have measured the loss coefficient of simple bending-loss transducer shown schematically in Fig. 1. The structure consists two mating, ridged plates (2.5 cm x 6 cm). fiber is placed between and compressed with a variable load, resulting transmission measured. investigated response various types also effects initial launch conditions. Figure 2 shows data from short (2-m) length Corning step-index fiber.
