DTS Sampling Resolution via Delay Line Segmentation

The patent segments the sampling process by using multiple low-frequency ADC cards instead of a single high-frequency ADC card. Each ADC card operates at a lower frequency but collects data at different time segments, which when combined, achieve the same high sampling resolution as a high-frequency ADC would provide. This segmentation approach reduces heat generation and cost while maintaining measurement precision.

The patent employs periodic action by having multiple ADC cards sample data at periodic intervals with different phase offsets. The sampling is performed in periodic cycles where each ADC card samples at a lower frequency, but the combined periodic sampling from multiple cards achieves high effective sampling rate. This periodic sampling strategy reduces power consumption and heat generation compared to continuous high-frequency sampling.

The patent segments the expensive high-frequency ADC function into multiple cheaper low-frequency ADC cards. Instead of purchasing and using a single expensive high-frequency ADC card, the system uses multiple affordable low-frequency ADC cards that collectively provide the same sampling resolution. This segmentation significantly reduces system cost while maintaining measurement precision.

The patent creates multiple copies of the sampling function using identical low-frequency ADC cards. Each ADC card is a copy that performs the same sampling function at a lower frequency. By having multiple copies that sample at different times, the system achieves high sampling resolution without needing an expensive high-frequency ADC card. This copying approach reduces cost while maintaining performance.

The patent segments the sampling task across multiple ADC cards, each operating at lower frequency and lower cost. By combining the segmented data from multiple cards, the system achieves high spatial resolution without requiring any single ADC card to operate at high frequency. This segmentation allows cost-effective low-frequency ADC cards to deliver high-resolution results when their outputs are merged.

The patent merges the data from multiple low-frequency ADC cards to achieve high spatial resolution. Instead of relying on a single high-frequency ADC card, the system combines the sampled data from multiple lower-frequency ADC cards through merging algorithms. This merging process reconstructs high-resolution temperature profiles while using cost-effective lower-frequency hardware components.

The patent introduces an intermediary timing mechanism that decouples the laser pulse triggering from the ADC sampling trigger. Instead of using the laser pulse directly as the trigger (which causes jitter), an intermediary timing system uses a stable clock reference and delay generators to synchronize sampling with the laser pulse timing. This intermediary approach eliminates signal jitter while maintaining accurate timing.

The patent applies preliminary action by pre-calculating and pre-setting the timing parameters for ADC sampling based on the laser pulse characteristics. The system uses a stable clock reference to pre-determine the optimal sampling moments and sets delay generators accordingly. This preliminary timing setup ensures that sampling occurs at the correct moments without jitter, as the timing is established before the actual sampling event.
