What is the difference between sampling frequency and true spatial resolution?

• A. Sampling frequency is set by pixel size; true spatial resolution also depends on system blur; high sampling without adequate optical resolution can cause aliasing.
• B. Sampling frequency equals pixel size; true spatial resolution depends only on detector pixel size.
• C. Sampling frequency is determined by fill factor; true resolution is independent of blur.
• D. Sampling frequency determines color depth.

Answer: (A)
