ABSOLUTE DISTANCE METER BASED ON AN UNDERSAMPLING METHOD |
摘要 |
A measurement system includes a signal generator producing an RF modulation frequency and sampling frequency and sending the sampling frequency to an ADC, and sending the RF frequency to modulate a first light source to produce a first light; an optical system sending a portion of the first light to a reference optical detector a portion of the first light out a measurement device to a target that returns a second light to the optical system which sends the second light to a measure optical detector, the reference and measure optical detectors converting the optical signals into corresponding electrical signals; a first ADC channel receiving the electrical measure signal and producing digital measure values; a second ADC channel receiving the electrical reference signal and producing digital reference values; and a processor receiving the digital measure and reference values and calculating the device to target distance.
