Lattice constant
Lattice constant / Постійна решітки
In a crystal, atoms are arrayed uniformly to form a crystal lattice. The lattice constant is a measure that defines the size of the unit lattice, which is the minimum unit of a crystal lattice.

Linearity
Linearity / Лінійність
When light strikes a photodiode, a photocurrent is generated in proportion to the incident light level. This proportional relationship between the photocurrent and incident light level is called the linearity. If the incident light level becomes higher than a certain level, then the linearity begins to deviate, causing the photocurrent in the photodiode to saturate. The light level causing saturation depends on the photodiode structure and also varies according to the load resistance, reverse voltage, and the size of the incident light spot.

Lookup table (LUT)
Lookup table (LUT) / Таблиця пошуку
A data structure that replaces a complicated calculation pro- cess with a simple array for economizing the process. The calculation processing time can be reduced by storing an array of precalculated values and extracting the necessary data from the matrix as needed.

Luminous gain
Luminous gain / Коефіцієнт підсилення світла
The ratio of the phosphor screen's luminous emittance (lm/m2) to the illuminance (lx) incident on the photocathode.
