Lateral resolution is measured in units of ______.

Lateral resolution is measured in units of ______.

• A. Units of distance
• B. Units of time
• C. Units of frequency
• D. Units of intensity

Answer: (A)

Lateral resolution describes how close two objects can be side-by-side in the image and still be shown as two separate features. It’s about a physical distance on the image plane, so it’s expressed in units of length (for example, millimeters). This is different from axial resolution, which concerns distance along the direction of the beam and is often related to pulse duration. Time units would correspond to time-of-flight or range, frequency relates to wavelength and how the image forms, and intensity refers to brightness, not separation. So lateral resolution is measured in units of distance.
