| Abstract: | In this work, the 2-dimensional images of a-tracks in CR-39 detectors have been analyzed in terms of
grey values to obtain the critical information such as track length and angle,
which usually cannot be obtained by conventional optical microscopes. A
user-interactive code has been developed for the automated track detection
based on the average grey values and light intensity in the vicinity of
individual tracks. The code automatically identifies the tracks, and determines
the track density, length, major axis, minor axis, eccentricity, incidence
angle, etc. and provides a 2-D cross-sectional view of the detected tracks. The
algorithm efficiently segregates individual tracks from the overlapped
multi-tracks present above a preset depth (threshold) provided by the user with
the option of manual rejection of track like manufacturing defects in the
detector. This method can eventually be applied for neutron spectrometric
studies, where the length and angle information of the recoil tracks in solid
polymeric track detectors are crucial. |
