摘要:
A light processor (such as a spectrometer) providing wavelength equalization for a sample pathway and a reference pathway by actuation of a light amplitude modulator. A chemometric processor including a light amplitude modulator capable of performing chemical analysis by applying weights to wavelengths of light, thereby reducing the need for electronic post processing.
摘要:
A strength monitor for a wavelength-division multiplexed (WDM) communication system in which the carriers comprising WDM signal do not need to spatially separated to determine their strengths. The strength monitor provides local modulation of a carrier to measured. In some embodiments, a strength monitor uses a digital channel equalizer to modulate a given carrier whose strength is to be measured.
