Through the Looking-Glass

The potential of holography in measurement science was noted early in its history. Photogrammetry, its origins in aerial photographic reconnaissance, had existed since the First World War and had quickly become an important tool in map making.

Photogrammetry is the use of photography for measurement purposes. By analogy, the use of holography in measurement is termed hologrammetry.

An early discovery in photogrammetry was the ability to estimate the heights ...
