LDI

LDI is an acronym that can refer to several concepts across different fields. In entertainment technology, LDI stands for Lighting Dimensions International, a major trade show and conference for lighting, stage design, and related technologies. The event gathers designers, technicians, and vendors to showcase products, share knowledge, and discuss industry trends, serving as a focal point for the live event and stagecraft community.

In medical imaging and vascular assessment, LDI commonly denotes Laser Doppler Imaging, also known as Laser Doppler Perfusion Imaging. This noninvasive technique maps microvascular blood flow in tissue by analyzing Doppler shifts of laser light scattered by moving red blood cells. LDI systems produce perfusion maps used in burn wound evaluation, skin viability assessment, and various microcirculation studies.

In computing and embedded systems, LDI is an assembly language mnemonic meaning Load Immediate. It is used in certain architectures (notably AVR microcontrollers) to load a constant value directly into a register. The instruction is architecture-specific and typically restricted to a subset of registers.

Other uses of LDI exist in different organizations, programs, and contexts that adopt the acronym for their names. Because LDI is context-dependent, disambiguation is often required when the term appears.
