[An improved method for inversion of particle size distribution from scattering spectrum]

Area of Science:

• Optics and Photonics
• Materials Science
• Data Analysis

Context:

• Particle size distribution measurement is crucial in various scientific fields.
• Diffraction measurements from scattering spectra are susceptible to noise, complicating analysis.
• Existing inversion methods often struggle with noise reduction without compromising data integrity.

Purpose:

• To develop an improved inversion method for particle size distribution measurement.
• To reduce noise in diffraction measurements derived from scattering spectra.
• To enhance the accuracy and reliability of particle size analysis.

Summary:

• An improved Chin-Shine integral transform method incorporates a 'regulate function' to eliminate noise in diffraction measurements.
• This novel approach effectively suppresses noise without altering the peak characteristics of the inversion spectrum.
• The method was validated using a linear CCD detector array, demonstrating significant improvements over previous techniques.

Impact:

• The improved method offers a feasible and effective solution for accurate particle size distribution analysis.
• Optimizing sampling angles through focal length selection further mitigates inversion spectrum issues.
• Successful application in actual measurements confirms the practical utility and robustness of the enhanced technique.
