... Back-illuminated CCDs with resolution greater than 4096 x 4096 elements, frame rates in excess of 10,000 frames per second, and noise lower than 3 electrons rms. have been independently demonstrated. Additionally, back-illuminated CCD cameras have been shown well suited for significant low light level imaging applications. However, the application of back-illuminated CCDs for night vision applications requires that all performance characteristics be optimized in a single manufacturable device. ...

Next: CCD Scientific Performance Up: CCD Operation Previous: CCD Operation . A visible light photon releases only one electron-hole pair, and consequently many photons must be collected in each pixel for a measurable signal to be produced. ... This use as an imaging X-ray spectrometer requires that no more than one photon is incident on each pixel in any image frame, which imposes a requirement that image collection times be limited to ~seconds for typical astronomical applications. ...

... Astrophysics Group . ... MRAO Telescopes . ... A radio telescope consists of one or more directional receiving aerials connected to very sensitive amplifiers. Since radio wavelengths range from millimetres to about 10 metres, the actual form of the aerials can vary greatly; many are parabolic dishes with very precise surfaces, while others, like the Cambridge Low-Frequency Synthesis Telescope (right), are similar to television aerials. ...

Chaotic oscillators based on RC-elements and nonlinear amplifiers with sigmoid function only are discussed. The analysis of the structure a number of well-known oscillators is carried out. On the basis of that analysis the structure of the oscillators which consist of RC–elements and op-amps only and capable to show chaotic oscillations is suggested. ...
