AI Technical Summary

Benefits of technology

This technology uses a special type of circuit called an LPF (low pass filters) to improve the accuracy at which signals are captured during certain periods when they're being measured or analyzed. By doing this, it becomes easier for these measurements to be done with lower speeds than what was previously possible due to faster analog-converters.

Problems solved by technology

Technological Problem: Current Optical Sampling Methods are limited because they require expensive equipment such as electronics to accurately analyze large amounts of light at very fast speeds. Additionally, current techniques involve capturing only small pulses from one direction over multiple directions simultaneously which requires complex hardware designs.

Abstract

The invention relates to a nanosecond level pulse peak value detection method and belongs to the technical field of optical communication. According to the method, a nanosecond level pulse signal is broadened through a low-pass filter, then, a clock signal obtained after phase position adjustment is triggered, and therefore an analog-digital converter can sample data more accurately. Under the condition that a high-speed analog-digital converter is not needed, a nanosecond level pulse signal peak value can be detected. With the detection method, the requirement for the sampling rate of an analog-to-digital conversion unit can be lowered, the method is simple and easy to perform, and cost of the needed devices is low.
