Subsidence and uplift mechanisms within the South Caspian Basin: insights from the onshore and offshore Azerbaijan region

A laserlighting system of beam shaping, delivery, and the retroreflection of laserlight on specially designed markersto reduce the problems associated with the illumination of markings, signage, and reflectors installed in northern climates. The laserlighting system employs employ visible and reflective laserbeam lighting sources to provide illumination of airport runwaysand taxiways, preferred approach and departure routes, seaplane base landing areas, marine waterways, as well as to assist in searchand rescueoperations. The laserlighting system may be a laserlighting post or a laserlighting unit for providing radiation along a surface that includes at least one laserfor producing a beam of coherent visible or reflective radiation, and a glass plano-convex cylindrical lenswhich has an aspherical convex cylindrical surface for generating a laserline which is uniformally illuminated from end to end. The laserlighting post includes a mounting column which has an access door for providing access to a tilt switch assembly and an AC/DC power adapter unit. The mounting column is attached to a base plate by a frangiblecoupling. The laserlighting system also includes an omni-directional, retroreflective marker which is not permanently installed thus making replacement, maintenance and snow removalmuch easier.
