Momentum collimation in a high-intensity rapid cycling synchrotron (RCS) is a very important issue. Based on the two-stage collimation principle, a combined momentum collimation method is proposed and ...

The paper presents an optical method based on auto-collimation to simultaneously measure five degrees of freedom error motions of the rotary axis. The proposed method ...

We present a collimation technique based on a double grating system to locate with high accuracy an emitter in the focal plane of a lens. Talbot self-images are projected onto the second grating ...

Abstract: With the high angle measurement precision, theodolite has been widely used in Spacecraft Assembly alignment. However, the use of theodolite is connected with manual operation and judgment of ...

In my opinion, the Bahtinov mask is one of the most useful inventions for astrophotography. The traditional use of a Bahtinov mask is for focusing a telescope only and is not used for collimation of ...

There are elegant and inexpensive methods to collimate the Hyperstar, despite its tight tolerances measured in microns. Many users of Starizona’s Hyperstar system manage to configure their image ...
