What determines the appropriate laser (5 kHz – 50 kHz) system for the job?
The pulse repetition rate for power line surveys generally affects only the point density. It is the final product specifications that determine the appropriate points density. Equal points densities can be achieved with different systems, starting from 5 kHz to modern 50 kHz. Important factors to consider are that modern 50 kHz systems are higher in capitalization costs (more dollars per operational hour); consume more power, greater in size and weight – which requires bigger (more expensive) helicopters. For power line surveys, the flight speed and altitude above ground level is generally independent of pulse repetition rate of the system. Altitude at which the aircraft flies is limited by the visual tracking of the power line from the pilot’s seat – most pilots navigate visually using the monitors and cameras to “fine tune”. The average flight speed is affected by curvatures of the lines. It should be also noted that the greater the repetition rate the greater amount of data, which
