Optical theory of Camouflage physics is still camouflage engineering has been invented for defence protection. The invention of PhD thesis hasis optical theory can be implemented by defence scientists to explore camouflage theory, color engineering,products and multidimensional branches of optical technologies. Advancement in ultraviolet-visible-near infrared (UV-Vis-IR) camouflage engineering, c has been designed for defence protection. Camouflage materials and physics has been explained through camouflage physics fortextiles and camouflage assessment against multidimensional combat backgrounds in UV-Vis-IR spectrums formaterials. This technique of camouflage engineering can be explored to defence protection. The concepts of UV camouflage, adaptive camouflagetechnology for the design and manufacturing of combat product against multidimensional combat backgrounds, and simultaneous camouflage in UV-Vis-IR spectrums are the invention of PhD thesis in camouflage engineering for defence protection. Photon theory of camouflage engineering has also been applied by imaging technology of hyperspectral camera and digital camera such as dry leaves, green leaves, tree bark-woodland combat background; water-marine combat background; sand-desertland combat background; stone-stoneland combat background; snow-snowland combat background; sky combat background; ice-iceland combat background and concrete-concreteland combat background (DGTWSICB). This is a new concept for contribution of mankind. Covel addition of camouflage technology for the engineering progress of camouflage product design. Hence, camouflage engineering has been briefly reported by “Anowar Hossain’s invention of camouflage physics at PhD School, first version submitted to Nobel committee for Nobel nomination in 2023 under affiliation of RMIT University”. http://dx.doi.org/10.13140/RG.2.2.29936.23048, https://doi.org/10.5281/zenodo.8286832
