原始语种摘要: Abstract(#br)Tracks lost during the etching process of an external mica detector can be quantified if the minimum retained dip angle, θ c , is known. Using confocal microscopy a series of planar images were obtained from different depths to a resolution of 0.2 μm. A method of identifying θ c from the modal dip angle is described. An image analysis system allows reconstruction of the tracks in three dimensions and track lengths measured for annealing studies. A robust algorithm is shown to identify tracks present within noisy images and identifies the modal dip angle in agreement with earlier results. This is the first time a fully automated system has been achieved. The results are encouraging but suggest that it might be necessary to decorate the tracks before imaging to obtain a better...
