Minimum resolvable contrast — The 1951 USAF Tri bar Resolution Test Target is a classic example of a three bar target for the MRC test. The target is typically illuminated by an integrating sphere irradiating in the visible spectrum. Minimum resolvable contrast (MRC) is a… … Wikipedia
Minimum resolvable temperature difference — (MRTD) is a measure for assessing the performance of infrared cameras, and is inversely proportional to the modulation transfer function. Typically, an operator is asked to assess the minimum temperature difference at which a 4 bar target can be… … Wikipedia
Modulation transfer function (infrared imaging) — The Modulation Transfer Function (MTF) is used to approximate the position of best focus of an infrared imaging system. In an imaging system, best focus is typically achieved when the MTF is between 0.4 and 0.6; most often at 0.5 (50% cutoff… … Wikipedia
Optical resolution — This article is about optical resolution in optics. For the method of separating enantiomers in chemistry, see Chiral resolution. Optical resolution describes the ability of an imaging system to resolve detail in the object that is being imaged.… … Wikipedia
Signal transfer function — The signal transfer function (SiTF) is a measure of the signal output versus the signal input of a system such as an infrared system or sensor. [cite book | title = The Optical Transfer Function of Imaging Systems | author = Tom L. Williams |… … Wikipedia
Signal to noise ratio (image processing) — The Signal to Noise Ratio (SNR) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) and therefore apply the 20 log rule to the pure SNR ratio. In turn,… … Wikipedia
Image resolution — describes the detail an image holds. The term applies equally to digital images, film images, and other types of images. Higher resolution means more image detail. Image resolution can be measured in various ways. Basically, resolution quantifies … Wikipedia
