To analyze, quantify, and compare the performance of infrared (IR) imaging devices, such as various types of focal plane arrays (FPAs), it is essential to have an in-depth understanding of their figures of merit. In this entry, we discuss a series of figures of merit that are applicable to both cooled and uncooled IR detectors and systems. We provide a

Analytical Figures of Merit for Multisensor Arrays
ACS Sensors, 2020Multisensor arrays employing various sensing principles are a rapidly developing field of research as they allow simple and inexpensive quantification of various parameters in complex samples. Quantitative analysis with such systems is based on multivariate regression techniques, and deriving of traditional analytical figures of merit (e.g ...

Figures of merit are values that denote the benefit of key material properties in terms of mechanical and thermal performance. Mechanical figures of merit relate to stiffness, strength, and mass. The stiffness of a material is proportional to its elastic modulus E, while the mass of a material is proportional to its density ρ.

Improved figures of merit for direct methods
Acta Crystallographica Section A Foundations of Crystallography, 1992The figures of merit (FOMs) proposed in a recent paper [Cascarano, Giacovazzo & Viterbo (1987). Acta Cryst. A43, 22–29] are modified to improve their efficiency. It is shown that FOMs based on psi-zero triplets and FOMs based on the distribution of the concentration parameter α can be treated by the same mathematical formalism.

Loudspeaker system figures of merit
IEEE Transactions on Audio and Electroacoustics, 1973The loudspeaker system small-signal figure of merit is a useful performance criterion that must be evaluated and used with some care. In practice, this figure of merit is significantly reduced by enclosure dissipation, including that contributed by filling materials.

ALTERNATIVE FIGURES-OF-MERIT IN DIGITAL MAMMOGRAPHY
Radiation Protection Dosimetry, 2017The aim of this study is to explore the use of a quality (Q) factor in digital mammography as a figure-of-merit. Q factors take a reference value into account and can be compared to a theoretical value. They are also intended to summarise the performance of any unit based on a number.

Figure of merit for thermoelectrics
Journal of Applied Physics, 1989Theoretical calculations are presented for the figure of merit Z in thermoelectrics. The maximum values of Z are obtained in semiconductors which are doped so that the chemical potential is near the band edge. The highest Z is related to the B parameter of Chasmar and Stratton [J. Electron. Control 7, 52 (1959)].

ACM SIGACT News, 1990
Science has marched on despite the appearance of the original "Figures of Merit" [18]. The purpose of this survey is to bring the community up to date on the most recent bounds, so that we may collaborate to improve them.

Thermomagnetic Figure of Merit: Bismuth
Journal of Applied Physics, 1963The asymptotic value of the isothermal thermomagnetic figure of merit is obtained for a two-band multivalleyed semiconductor or semimetal where the concentration of holes and electrons is equal. The bismuth band structure is used as a specific model. It is shown that at strong magnetic fields the isothermal Nernst coefficient Njii is independent of the

Stretchable Figures of Merit in Deformable Electronics
Advanced Materials, 2015Stretchable electronic systems accommodate strain in various ways-from the intrinsic mechanical properties, through composite structures, by the formation of cracks, or with other mechanisms. This has produced some imprecision in the literature on what is meant by the term "stretchable."
