A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an …

In communication applications like the internet, the most simple form of optical communication is with a single fiber consisting of a single wavelength laser TX/RX scheme. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber by using different …

Quantum technology (QT) applies quantum mechanical properties such as quantum entanglement, quantum superposition, and No-cloning theorem to quantum systems such as atoms, ions, electrons, photons, or molecules. Quantum bit is the basic unit of quantum information. Whereas in a classical system, a bit is either in one state or the another. …

Guided missiles work by tracking the moving target’s location in space by specific methods (e.g. using a radar or following its heat signature), chasing it down, and finally hitting it with accuracy. Guidance systems in missiles can be of various types, which serve different operational purposes. Homing guidance systems control the …
