摘要： A device that uses two intensity modulated frequency combs to measure distances with high precision and high data acquisition rate without any moving parts and without length ambiguity that is inherent conventional ranging based on two frequency combs. A modulation signal having a repetition rate identical to the repetition rate difference between the two combs is used to do a direct time-of-flight length measurement, hence avoiding the given length ambiguity while harvesting the increased precision of the dual-comb approach.

摘要： A method for matching one or more channels to a reference channel in a multiple-channel detector having a digital output, the method including: receiving an analog-to-digital unit (ADU) input value from the multiple-channel detector for each channel; and replacing the ADU input value by an output value corresponding to each channel from a look up table (LUT); wherein the LUT is created by taking a relative intensity ratio of signals from each channel compared to the reference channel over a range of voltage values; calculating a signal value on the detector that generates a specific ADU value across the entire ADU range of the detector; interpolating the relative intensity ratios to obtain ratios corresponding to the calculated signal values for each channel; and dividing the each of the specific ADU value by the corresponding interpolated ratio to obtain the corresponding output value for each channel.
