A Python tool converting geophone to DAS response

<p>This script delineates the development and validation of a specialized Python tool devised to enhance geophysical data analysis on Distributed Acoustic Sensing (DAS). The tool skillfully converts geophone measurement to DAS strain responses.</p>

<p>The input of the script contains continuous 3-component point displacement measurements from geophone, their corresponding Cartesian coordinate locations and a designated gauge length (depends on instrument). Through integration along the fiber within the established gauge length, the script output the equivalent numbers of DAS strain response. Featuring a sub-function convert velocity to displacement, this tool can also convert displacement/velocity to DAS strain/strain rate response. The time complexity is limited by the spacing of geophone and gauge length, but acceptable for practical scenario where the number of continuous geophone measurements is less than 1000.</p>

<p>The tool has been validated through rigorous numerical experiments, wherein pseudo plane waves were generated and the result is compared with established plane wave analytical solutions. This contribution serves as a step towards refining data processing methodologies in geophysical studies, fostering a seamless and efficient transition to modern DAS technologies.</p>
