摘要： A salinity measuring apparatus to determine salinity of food includes a salinity sensing unit including a pair of measuring electrodes and a capacitor, a switching unit to switch a voltage of the capacitor of the salinity sensing unit, and a control unit to provide a pulse signal with a constant frequency to the switching unit and to determine the salinity of the food which is in contact with the measuring electrodes of the salinity sensing unit based on when the voltage of the capacitor reaches a reference voltage. By providing the pulse signal with the constant frequency to the switching unit, it is possible to minimize the internal impedance variation of the capacitor and to more accurately measure the salinity of the food. Since a period when the voltage of the capacitor is substantially “0” is present, it is possible to minimize accumulation of ions in the measuring electrodes.

摘要： A time resolved spectroscopy system and method are provided using digital processing techniques of a low power, continuous wave signal generated by a continuous wave light source, such as a cw laser. Time elapse is determined by measuring the time shift of the signal modulation sequence using the cross correlation of a return signal with the reference signal. The high resolution time delay is introduced at the start of each modulation cycle and the high resolution measurement is constructed by interlacing a data set based on the delay information. The high resolution TRS or fluorescence measurement is achieved by correlation calculation of the measured data and the reference code and deconvolving the autocorrelation function of the reference code.
