Simple smoothing technique to reduce data scattering in physics experiments

摘要: This paper describes an experiment involving motorized motion and a method to reduce data scattering from acquisition. Jitter or minute instrumental vibrations add noise detected signal, which often renders small modulations of graph very difficult interpret. Here we describe amongst points the signal measured by photodetector that is scanned in direction parallel plane rectangular slit during computer-controlled diffraction experiment. The smoothing technique investigated using subsets many A limit for number subset determined results based on trend avoid severe changes shape averaging procedure. simple can be achieved any type spreadsheet software.
