Analyzers with time variation based on color-coded spatial modulation

摘要: A filter arrangement can transmit and/or reflect light emanating from a moving object so that the has time variation, and variation include information about object, such as its type. For example, segments of path be transmitted/reflected through positions assembly, transmission functions sufficiently different occurs in between segments. Or segment component which simpler are superimposed, accordance with superposition two non-uniform functions. Many arrangements could used, e.g. have one Time-varying waveforms sensing results compared to obtain spectral differences. The arrangement, practical commercial embodiment, manufactured disposable, used point-of-care device for use practically anywhere, at low cost, also implemented an in-line monitoring system.
