... capabilities. This is specially true for spectropolarimetric measurements, when the Stokes profiles of spectral lines are often detected by measuring relative differences in signals of the order of 10-3 or less. We often believe that key to success is increasing photon counts, and that having collec ...

Using this technique, the navigator at sea could measure the angle between the moon and a celestial body, calculate the time at which the moon and the celestial body would be precisely at that angular distance and then compare the ship’s chronometer to the time back at the national observator ...

Reflecting instrument

Reflecting instruments are those that use mirrors to enhance their ability to make measurements. In particular, the use of mirrors permits one to observe two objects simultaneously while measuring the angular distance between the objects. While they are used in many professions, they are primarily associated with celestial navigation, as the need to solve navigation problems, in particular the problem of the longitude, was the primary motivation in their development.
