摘要:
An optical domain spectrum analyzer/channelizer employs multicasting of an analog signal onto a wavelength division multiplexing grid, followed by spectral slicing using a periodic optical domain filter. This technique allows for a large number of high resolution channels. Wideband, 100% duty cycle, spectrum analysis or channelization is made possible permitting continuous time wideband spectral monitoring. The instantaneous bandwidth of the spectrum analyzer/channelizer is equal to the full radio frequency bandwidth of the analyzer/channelizer.
摘要:
The present invention relates to nanoscale transduction systems that produce reversible signals to facilitate detection. In one respect, the invention relates to the analysis of molecular binding events using higher order signaling nanoscale constructs, or “nanomachines”, that allow nanostructures to be individually detectable, even in the midst of high background noise. Such systems are particularly useful for improving the performance of rare target detection methods, as well as being generally useful in any field in which sensitivity, discrimination and confidence in detection are important.
