👉 Projection engineering is a specialized field within optics and acoustics that focuses on the design, development, and optimization of systems to project signals or images over long distances with high fidelity and efficiency. This involves the manipulation of light or sound waves using various optical components like lenses, mirrors, and diffractive elements to control their direction, focus, and intensity. Key aspects include beam shaping, aberration correction, and alignment precision to ensure that the projected signal maintains its quality and relevance over extended ranges. Applications range from laser communications and remote sensing to projection mapping and optical data transmission, where the goal is to deliver clear, high-resolution images or data streams with minimal distortion and energy loss.
