Abstract: A rotation detection kit, comprising: a beam source; a receiver comprising at least one beam intensity sensor; a polariser device for location in the path of a beam emitted from the beam source and received by the beam sensor; and a modulator. The modulator is configured to modulate at least one of i) the beam source and ii) a beam emitted by the beam source to create a discretely varying polarisation orientation thereby defining first and at least second temporally spaced beam portions. The temporally spaced beam portions are incident on the polariser device and the beam sensor and have substantially identical profiles and at least an initial common propagation axis toward the polariser device.

Abstract: A rotation detection kit, comprising a source for generating at least a first polarized beam emitted along a propagation axis, a receiver comprising at least a first beam intensity sensor and an analyzer. The analyzer comprises a first polarizer device for location in the at least first polarized beam between the source and at least first beam intensity sensor. The first polarizer device is configured such that the receiver can measure rotation between the source and the analyzer about a first axis that is non-parallel to the propagation axis based on the at least first beam intensity sensor's output.
