Abstract

Resolution has been in use so long that it is thought of as a fundamental property that uniquely determines system performance. There are four different types of resolution: 1) temporal, which is the ability to separate events in time; 2) grayscale, determined by the analog-to-digital converter design, noise floor, or the display capability; 3) spectral; and 4) spatial. An imaging system operating at 30 Hz frame rate has a temporal resolution of 1/30 sec. Grayscale resolution is a measure of the dynamic range. The spectral resolution is simply the spectral bandpass (e.g., visible, NIR, etc.) of the system. This chapter covers spatial resolution.
