Dependent upon the processing of the normalized error magnitude signals, the phase of the sampling clock signal is either shifted or maintained until the next sampling point.
Moreover, it can be used to yield a direct representation of the sample's phase contrast information without the need for additional specialized post-acquisition image analysis.
The sensor may be connected with a processor running a program to retrieve phase information from the sample from the first and second image received by the sensor.
Sampling phase converting means (8) corrects, based on the phase correction amount (Δb,Δt) from the phase difference calculating means (4), the phase of the sampling of the composite color video signal.
Amplitude and/or phase images of the sample are reconstructed based at least in part on the recovered lost phase information.
A first measurement identifies the phase of the sample and/or the solids fraction of the sample.
