Technology
Dynamic Image Analysis (DIA) Technology
The BeVision D3 Series employs advanced Dynamic Image Analysis (DIA) technology to deliver fast, accurate, and reproducible particle size and shape measurements.
During analysis, dispersed particles pass through a precisely defined detection zone. Uniform background illumination across the entire field of view creates high-contrast particle projections, which are captured in real time by a dual high-speed camera system. One camera focuses on coarse particles, while the other simultaneously captures fine particles, enabling complete size and shape distribution analysis across a wide measurement range in a single run.
Why DIA Method?
Dynamic Image Analysis (DIA) combines the strengths of traditional and modern particle characterization techniques while eliminating their limitations. By analyzing individual particles in motion, DIA delivers accurate, representative, and reproducible results for both particle size and shape—across a wide measurement range.

| Repeatability | 0.04% | 0.04% | 0.07% | |
| Example: Cracked Soybeans | ||||
| Even for cracked soybean particles with wide size distributions and highly irregular shapes, the repeatability of D50 remains better than 0.5%, confirming reliable performance for real-world samples. | ||||
| D10 | D50 | D90 |  |
|
| Mean /μm | 994.74 | 1056.32 | 1112.13 | |
| Std. Dev /μm | 0.39 | 0.43 | 0.76 | |
| Repeatability | 0.04% | 0.04% | 0.07% | |
2. Comprehensive Particle Size & Shape Analysis
The BeVision DIA Software provides 37+ particle size and shape parameters, enabling thorough characterization and objective evaluation of diverse particle morphologies.
| Example: Petroleum catalyst | |
| Rod-like catalyst particles are characterized in terms of length, diameter, and curvature. The measurement results closely align with intuitive visual assessments, confirming the accuracy and relevance of DIA-based morphology analysis. | |
 |
 |
3. Accurate Determination of Low-Content Oversize Particles
By leveraging advanced digital imaging technology and highspeed image capture, BeVision D3 Series achieves ultra-high detection efficiency. Even oversize particles present at extremely low concentrations can be accurately identified and quantified.
| Example: Colorants |
| Over 1 million colorant particles were analyzed within 6 minutes. The resulting size distribution revealed a small fraction of oversize particles, and captured images confirmed that each oversize particle was an agglomerate composed of multiple smaller colorant particles. |
 |
4. Ultra-High Resolution for Narrow Distributions
The BeVision D3 Series analyzes every individual particle captured during measurement and performs statistical analysis across the full particle population, achieving single-particle resolution.
| Example: Abrasives |
| In abrasive materials, both oversize and undersize particles can negatively affect grinding performance. The BeVision D3 Series precisely quantifies the content of oversize and undersize particles, while also providing particle shape analysis to evaluate abrasive sharpness. |
 |
5. Mixture Analysis
The BeVision DIA Software is a powerful data analysis platform that enables separation and analysis of mixed particle systems. Particle mixtures can be classified and filtered based on size, shape, or multiple parameters, allowing each fraction to be analyzed independently within a single dataset.
| Example: Beans |
 |
| Direct measurement of mixed beans produces a bimodal particle size distribution (PSD). The smaller peak corresponds to mung beans, while the larger peak represents red beans. By applying size-based filtration, the software separates red beans and mung beans from the mixed dataset, enabling independent analysis of each component without additional measurements. |
6. Fully Comparable with Sieving Results
The BeVision D3 Series uses a sieve-equivalent diameter aligned with the fundamental principles of sieving, delivering particle size distributions (PSD) that are highly consistent with traditional sieve analysis. Its dedicated sieve correlation function automatically compensates for systematic differences related to measurement principles, particle shape and statistical effects, and directly outputs sieving-correlated PSD results.
| Example: Fertilizer |
| PSDs measured by the BeVision D3 show excellent agreement with sieve analysis results. Users can switch seamlessly from mechanical sieving to the BeVision D3 system, significantly improving testing efficiency while reducing labor costs. |
 |
7. Thickness Measurement of Flaky Particles
The BeVision D3 Series is capable of capturing crosssectional images of flaky particles during measurement, enabling automatic and direct thickness measurement.
| Example: Soybean meal |
| The thickness of the flaky soybean meal residue after pressing directly reflects the residual oil content. Conventional thickness measurement relies on manual caliper measurements of individual particles, resulting in extremely low efficiency and poor representativeness. The BeVision D3 system automatically measures and outputs the thickness distribution and mean thickness, significantly improving measurement efficiency, repeatability, and statistical reliability |
