我们提出了一个实验的机会，为未来测量可能违反牛顿1/r{sup 2}定律在0.1-10米的范围内使用动态重力场发生器（DFG），并利用现代干涉技术的特殊灵敏度。将DFG放置在干涉仪的悬挂测试质量之一附近会产生局部重力场的变化，该变化可以以高信噪比进行测量。在零实验配置中使用多个DFG使我们能够测试与成分无关的非牛顿引力显着超出目前的限制。先进的第三代引力波探测器代表了当今干涉测距的最新技术，因此，我们通过它们的灵敏度来说明该方法，以强调可能的科学范围。然而，由于引力波探测器的技术细节，DFG可能需要专门的定制配置干涉测量。然而，我们得到的灵敏度测量是一个坚实的基线，表明它是可行的，考虑探测到原始参数的数量级远远超出目前的实验限制，显着切入理论参数空间。
We present an experimental opportunity for the future to measure possible violations to Newton's 1/r{sup 2} law in the 0.1-10 m range using dynamic gravity field generators (DFG) and taking advantage of the exceptional sensitivity of modern interferometric techniques. The placement of a DFG in proximity to one of the interferometer's suspended test masses generates a change in the local gravitational field that can be measured at a high signal to noise ratio. The use of multiple DFGs in a null-experiment configuration allows us to test composition-independent non-Newtonian gravity significantly beyond the present limits. Advanced and third-generation gravitational-wave detectors are representing the state-of-the-art in interferometric distance measurement today, therefore, we illustrate the method through their sensitivity to emphasize the possible scientific reach. Nevertheless, it is expected that due to the technical details of gravitational-wave detectors, DFGs shall likely require dedicated custom-configured interferometry. However, the sensitivity measure we derive is a solid baseline indicating that it is feasible to consider probing orders of magnitude into the pristine parameter well beyond the present experimental limits significantly cutting into the theoretical parameter space.
