A Reflecting Prism for Sokkia Total Station.
Home Studio Photography - RAW Cont. Tiff ad23 dn df Tiff 13.0 MB.
A Prism Pole & Total Station (Surveying Instrument) are used to measure the elevation of a specific ground point by using a sight level, which is essential to get accurate results.
With the prism method, the Total Station sends out invisible infrared waves that are reflected by the Prism, which is typically attached to a pole.
The total station calculates the prism's location or coordinates by measuring the Prism's position and knowing the precise angle and distance to that prism.
Apollo Missions to the Moon:
Five Prisms Panels were placed on the Moon ( Two were delivered by Apollo 11 and 14 crews in 1969 and 1971 respectively) so scientists back on Earth could fire lasers at them and accurately measure the distance between Earth and the Moon. While those prisms were placed there back in 1969, they are still being used today and have delivered an extraordinary amount of valuable information.
Note that the Nikon Camera Lens is reflected in the image!
