Random Pattern (Noise) Test Chart

High-Precision Texture & Noise Evaluation for Camera Systems

The Oklab Random Pattern (Noise) Test Chart is designed for precise measurement of image sensor noise, texture preservation, and signal-to-noise performance in professional camera calibration and quality control workflows.

Unlike uniform or repetitive targets, the random pattern provides a statistically uniform texture that minimizes aliasing and ensures accurate analysis of noise power spectral density (PSD). This makes it the ideal tool for evaluating both spatial noise characteristics and fine-detail retention in modern imaging systems.


Key Features

  • Random Texture Region – Enables accurate assessment of noise, sharpness, and texture reproduction without introducing pattern bias.

  • Gray Patch Reference Zones – Support noise PSD normalization and dynamic range analysis.

  • High-Precision Manufacturing – Printed or etched on matte substrates with consistent surface reflectance for stable results.

  • Multiple Substrates Available – Photographic paper, film, or glass options to suit laboratory or production environments.

  • Custom Sizes & Layouts – From compact sensor testing to full-format camera calibration, patterns can be customized to any dimension or contrast level.

  • Compatible Software – Compatible for Imatest, ColorTest, and other professional image-quality analysis tools.


Applications

  • Image sensor noise and SNR testing

  • Texture loss evaluation in ISP tuning

  • Machine vision camera quality control

  • Image compression and denoising algorithm validation

  • Dynamic range and low-light performance benchmarking
