Using the aOCT system we have taken these measurements for the first time, and as the system is portable it can be used in normal hospital rooms.  ...  The initial application of the system is research into obstructive sleep apnoea (OSA), a serious condition characterized by repetitive collapse of the upper airway during sleep and an independent risk  ...  Schemes achieving millimetre resolution have required very high peak power levels (undesirable for in vivo application) and long averaging times -these requirements make OTDR unsuitable for this application  ...

Millimeter-Precision Laser Rangefinder Using a Low-Cost Photon Counter

Andreas Eisele
Moreover, a high stability of the temporal behavior versus device mismatch, temperature, and voltage is of utmost importance.  ...  Construction or DIY (do it yourself) applications are a very price sensitive market; hence the overall system cost should be as low as possible.  ...  An FMCW-system has the advantage that the slope can be adjusted for a given application.  ...
