英文摘要Atmospheric optical turbulence intensity, quantified by the Fried parameter ( (Formula presented.) ), serves as a critical metric for astronomical site testing and selection. The Solar Differential Image Motion Monitor (SDIMM), adapted from the methodology of the Differential Image Motion Monitor (DIMM), is a dedicated instrument for daytime (Formula presented.) measurements. Conventional SDIMM systems typically employ telescopes with apertures ≥30 cm and reconstruct wavefront segmentation at the exit pupil, resulting in bulky configurations that impede portability. To address the demands of multi-site surveys, we developed a low-cost, portable SDIMM system that directly adopts the DIMM optical path without backend wavefront reconstruction, instead deriving (Formula presented.) through image processing algorithms. Integrated with a 20 cm aperture telescope, the system achieves a total weight of © 2025 by the authors.
