Image Quality Testing
Five connected notes on contrast, detail, uniformity, geometry, and stray light—each explored through both imaging and display measurements.
Start with contrastOne optical phenomenon. Two measurement paths.
A camera acquires an image; a display presents one. Both must preserve contrast, spatial detail, brightness relationships, and geometry while controlling unwanted light. Each note gives these two paths equal attention, with paired diagrams, measurement guidance, and focused calculators.

Measuring Image and Display Contrast
Choose a contrast definition that matches the feature, background, and viewing condition.

Contrast Transfer and Spatial Resolution
Measure how imaging and display systems preserve detail across frequency, field, and direction.

Illumination, Shading, and Luminance Uniformity
Separate smooth field variation, fixed-pattern structure, and random noise before correcting them.

Geometric Distortion and Image Mapping
Measure departures from the intended geometry and define the distortion convention before comparing results.

Stray Light, Flare, and Contrast Loss
Trace unwanted light paths in imaging and display systems before choosing a measurement or mitigation.

A useful specification names the metric and the test conditions. Your application determines the acceptance limit.
