Our sight is a remarkable ability that allows us to interpret the world around us. Sunlight, with its high intensity and rich variety of wavelengths, plays a vital role in shaping our visual experience. The science of day optics explores the intricate mechanisms by which light interacts with the eye, ultimately leading to the formation of pictures.

Thermal imaging utilizes the power of infrared radiation to depict the otherwise invisible world of heat. By measuring these variations in thermal energy, thermal cameras generate a visual representation known as a heat signature. These signatures {reveal{ hidden temperature differences, allowing us to observe hot and cold spots with accuracy. Appl
