HELIOGRAPHS:
A heliograph (from Ancient Greek helios meaning sun) uses reflecting mirrors that signals by flashes of sunlight (generally using Morse code). The heliograph was a simple but effective instrument for optical communication over long distances during the late 19th and early 20th century. Its main uses were military. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975.
Most heliographs were variants of the British Army Mance Mark V version. The heyday of the heliograph was probably the Second Boer War in South Africa, where it was much used by both the British and the Boers. During World War II, South African and Australian forces used the heliograph while fighting German forces in Libya and Egypt in 1941 and 1942.
Most heliographs of the 19th and 20th century were completely manual. The steps of aligning the heliograph on the target, co-aligning the reflected sunbeam with the heliograph, maintaining the sunbeam alignment as the sun moved, transcribing the message into flashes, modulating the sunbeam into those flashes, detecting the flashes at the receiving end, and transcribing the flashes into the message, were all done manually.
