What DEL pitch size is preferred to increase spatial resolution?

• A. Small DEL pitch
• B. Large DEL pitch
• C. Moderate DEL pitch
• D. Variable DEL pitch

Answer: (A)

Smaller detector element pitch yields higher spatial resolution because the image is sampled more finely. When each detector element covers a smaller area, you gather information from smaller portions of the scene, which reduces geometric blur from the sampling grid and increases the sampling density. This finer sampling lets you distinguish features that are closer together, improving the ability to resolve small details. If the pitch were larger, each element integrates over a bigger region, smoothing over fine features and limiting how close two points can be distinguished. Moderate or variable pitch wouldn’t maximize resolution in general, since the aim for higher resolution is achieved by making the sampling grid as fine as practical. Keep in mind that very small pitch can bring trade-offs like lower per-element signal and increased readout complexity, but for spatial resolution alone, a small pitch is the preferred choice.
