This involves aligning the system's physical capabilities, such as fiber length and spatial resolution, with the practical limits of data collection, including the volume of data generated. Adjusting these settings correctly is crucial for optimizing data quality while managing the data volume effectively. This balance ensures that the system meets the specific needs of each application without overwhelming storage or processing capabilities. 269 269 270 270 290 +[[image:1706510182174-365.png]] 291 + 292 + 293 + 294 + 295 + 296 + 297 + 298 + 271 271 === [[image:1706506304897-924.png]] === 272 272 273 273 [[image:1706506500585-231.png]]
