Litrani是一个通用的蒙特-卡罗程序，模拟ROOT提供的形状所描述的任何类型的设置中的光传播。每个形状可以由不同的材料制成。材料的介电常数、吸收长度和扩散长度可取决于波长。介电常数和吸收长度可以是各向异性的。体积的每个面部分或全部与另一体积的面接触，或者覆盖有具有吸收、反射和漫射的限定特性的一些包裹物。当与另一个体积的另一个面接触时，在两个面之间存在具有宽度d和索引n的薄片的可能性。该程序有各种光源：自发光子，来自光纤的光子，粒子交叉产生的光子或电磁簇射产生的光子。所发射的光子的时间和波长谱可以再现任何闪烁谱。可以指定光电管、APD或任何一般类型的表面或体积检测器作为检测器。目的是跟踪每个光子，直到它被吸收或检测到。该程序要提供的信息是探测到的光子的比例，以及这些光子到达的时间分布，或者光子可能丢失的各种方式。(C)2002 Elsevier Science B.V.保留所有权利。
Litrani is a general purpose Monte-Carlo program simulating light propagation in any type of setup describable by the shapes provided by ROOT. Each shape may be made of a different material. Dielectric constant, absorption length and diffusion length of materials may depend upon wavelength. Dielectric constant and absorption length may be anisotropic. Each face of a volume is either partially or totally in contact with a face of another volume, or covered with some wrapping having defined characteristics of absorption, reflection and diffusion. When in contact with another face of another volume, the possibility exists to have a thin slice of width d and index n between the two faces. The program has various sources of light: spontaneous photons, photons coming from an optical fibre, photons generated by the crossing of particles or photons generated by an electromagnetic shower. The time and wavelength spectra of emitted photons may reproduce any scintillation spectrum. As detectors, phototubes, APD, or any general type of surface or volume detectors may be specified. The aim is to follow each photon until it is absorbed or detected. Quantities to be delivered by the program are the proportion of photons detected, and the time distribution for the arrival of these, or the various ways photons may be lost.
