    Abstract: A method and system for performing color print quality monitoring for a color printing process, the method includes determining a calibration distance (ZCAL) between a Spectrophotometer (140) and an associated calibration patch (310) that provides a maximum luminescence value (LMAX) detected by the Spectrophotometer. The Spectrophotometer (140) or patch distance (Z1) between the Spectrophotometer and a color calibration patch (320) printed on a sheet (155) is determined from a first maximum color patch luminescence value (L1). A first color reading of the color calibration patch is taken and a second color patch distance (Z2) between the Spectrophotometer and a different area of the color calibration patch (320) is determined to provide a second maximum color patch luminescence value (L2). A second color reading of the color calibration patch is taken and compared with the first color reading to determine if the printing process needs adjusting.

    Abstract: A system for simultaneous optical pathlength determination and remote chemical sensing of a sample disposed along an optical path. A modulated laser source configured for modulated light emission so that at least one spectral sideband with a sideband frequency is created, the modulated light emission is directed along the optical path and sideband frequency is varied over time. A detector is configured to detect transmitted light along the optical path and generate a detected light intensity signal. A frequency down-converter is configured to receive the detected light emission signal and generate a frequency down-converted light intensity signal. A demodulator is configured to demodulate the frequency of the down-converted light intensity signal and output an instantaneous frequency. A pathlength calculator is configured to determine an optical pathlength to the sample based on the instantaneous frequency. A frequency down-converted light intensity signal is simultaneously output for spectroscopic chemical sensing.
