The heliograph was standard issue for the British and Australian armies until the 1960s. I'm looking for a new mirror for my heliograph. There were many heliograph types. The heliograph had many great advantages.
look! i just made a heliograph!
The heliograph was used by the ancient egyptians as early as 500 C.E.
The cast of Trapped by a Heliograph - 1914 includes: Jessie Gill as Laura Lucas
an Egyptian man in the 500 c.e.
The captain of the ship used the heliographic light to signal the people in the sailboat.

A heliograph uses a mirror to reflect sunlight to a distant observer. By moving the mirror, flashes of light can be used to send Morse code. The heliograph was a simple but highly effective instrument for instantaneous optical communication over 80km or more in the 19th century.
A heliograph is a device for sending messages or signaling by flashing the sun's rays from a mirror.
Charles babbage invented many things including the cow catcher, the heliograph, the occul light house, analytical engien, and the diffrance engien.

Something that projects an image onto a wall in a darkened room is a Camera Obscura. A thing that projects an image of the sun, rather than of stuff in general, is usually called a Heliograph.

The Daguerreotype was supposedly invented by a Frenchman named Louis Daguerre. He may have stolen the idea from his partner, Nicephore Niepce who invented the heliograph and the first permanent camera photograph in 1826. As an aside, Daguerre's name is one of the 72 names inscribed on the Eiffel tower.
Many historians believe it was a Frenchman named Joseph Nicéphore Niépce, circa 1826, using a process called the heliograph to take a photo of a scene from nature. Other sources note the work of another French innovator, Jacques Louis Daguerre, who perfected a different way to take a photograph, circa 1839; it came to be known as the daguerrotype process.
No Thomas Edison did not invent photography. Employing data from the researches of Johann Heinrich Schulze-who, in 1727, discovered that silver nitrate darkened upon exposure to light-Thomas Wedgwood and Sir Humphry Davy, early in the 19th cent., created what we now call photograms. The French physicist, Joseph Nicéphore Niepce, made the first negative (on paper) in 1816 and the first known photograph (on metal; he called it a heliograph) in 1826.
Call me a nit-picker, but the camera obscura was not really a camera in the sense that it was not invented for the purpose of making photographs, and cameras don't develop pictures. If you're asking how long it took to make the first permanent exposure, it was about 8 hours. That being said, the camera obscura was used to make the first permanent photographic image (an image taken in nature). The first permanent image was a reproduction of an engraving and was a heliograph, not a true photograph.
telecommunication is the assisted transmission over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags or heliograph. In modern times, telecommunication typically involves the use of electronic devices such as the telephone, television, radio or computer. Early inventors in the field of telecommunication include Alexander Graham Bell, Guglielmo Marconi and John Logie Baird. Telecommunication is an important part of the world economy and the telecommunication industry's revenue was estimated to be $1.2 trillion in 2006.
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.
Wind Speed: Anenometer. ... Wind Direction: Wind Vane (with angular position indicator if remotely monitored) - there may be a "proper" term for it. ... Temperatures: Maximum & Minimum Thermometer. .... Humidity: Hygrometer. Rain-fall: Rain Gauge. .... Sunshine: not sure of its proper name but an instrument consisting of a glass ball that focuses the sunlight onto a specially-prepared paper, to create a mark whose length is proportional to the time of sunshine. (My inspired guess at "heliograph" produced on-line information about anything and everything except that to do with the weather!) .... Clouds: certain cloud and precipitation measurements are made using radar
Quoted from Wikipedia: Heliography (in French, héliographie) is the photographic process invented by Joseph Nicéphore Niépce around 1825, and which he used to make the earliest known permanent photograph from nature, View from the Window at Le Gras (c. 1826). The process used bitumen, as a coating on glass or metal, which hardened in relation to exposure to light. When the plate was washed with oil of lavender, only the hardened image area remained. The word has also been used to refer to other phenomena: for description of the sun (cf geography), for photography in general, for signalling by heliograph (a device less commonly called a heliotrope or helio-telegraph), and for photography of the sun.
Joseph Nicéphore Niépce is credited with producing the world's first photograph, a picture of buildings visible from the rooftop of his home made sometime in the summer of 1827. (It should be noted that some scholars suspect that the Shroud of Turin may be a photographic image, but if it is, it probably was not intentional. Niépce's image certainly was intentional.)The photograph is not much to look at, since the exposure lasted all day and the shadows swept across the whole scene as the sun moved. Even then the image was underexposed, but the sensitivity of Niépce's material was extremely low. Niépce called the image a "heliograph" since it was exposed by the sun.
