Measuring an Angle by Double Reflection
The observer looks straight at one object while light from the second object is reflected by two mirrors in turn into the same view. One mirror is turned until the reflected image sits exactly on the directly seen object, and the angle between the two objects is then read off. Because the light is reflected twice, the angle between the objects is twice the angle between the mirrors, and the instrument is graduated so the full angle is read directly.
