Imatest offers charts, software, and equipment to measure imaging system characteristics. Consider sensor resolution, field of view, working distances, and image quality factors when selecting test charts. Factors such as sharpness, chromatic aberration, distortion, color accuracy, noise, tonal response, texture response, dynamic range, contrast resolution, and flare are important to test. Slanted edges are efficient for sharpness and chromatic aberration measurements, allowing for detailed MTF mapping with Imatest slanted-edge analysis.
