Free space optical technology promises to revolutionize point-to-point communications systems. By taking advantage of their vastly higher frequencies, coherent optical systems outperform their radio counterparts by orders of magnitude in achievable d

Free-space continuous-wave laser interferometry using folded links has applications in precision measurement for velocimetry, vibrometry, optical communications, and verification of frequency transfer for metrology. However, prompt reflections from t

Geopotential and orthometric height differences between distant points can be measured via timescale comparisons between atomic clocks. Modern optical atomic clocks have residual instabilities on the order of 10^-18}, allowing height differences of a

We report on the development of a system called velocimetry by actively stabilised coherent optical transfer (VASCOT) that is capable of overcoming these challenges. VASCOT optically tracks the phase of the returned signal to allow for narrow-band ph

Free-space optical communications are poised to alleviate the data-flow bottleneck experienced by spacecraft as traditional radio frequencies reach their practical limit. While enabling orders-of-magnitude gains in data rates, optical signals impose

Corner cube retroreflectors are commonly used as cooperative targets in free-space laser applications. The previous literature suggests that due to path reciprocity, a retroreflected beam is self-corrected across a turbulent atmosphere and should sho

The presence of cancer, overt or occult, is thrombogenic to the individual. This has been recognised from the time of Armand Trousseau who, in 1865 [1], stated: “I have long been struck with the frequency with which cancerous patients are affected

Whereas the evidence base for surgical thromboprophylaxis has centred on elective orthopaedic surgery and subsequently been adopted in cancer surgery there is a good evidence base for the prevention of thromboembolic disease in other surgical special
