The instrument is called a Heliograph. It reflects sunlight to a remote station and is used in signaling and surveying by reflecting and then blocking the sunlight to create flashes of light, a bit like Morse Code but without the sound. The communication itself is called a Heilogram.

This device was used primarily by the military in the 19th and early 20th century. It was invented by Sir Henry Christopher Mance (1840-1926) of the British Army Signal Corps in 1869, and was first used in war. Amazingly, it can send messages over 100 miles.
