Abstract: A METHOD AND SYSTEM FOR PRODUCING A PPI DISPLAY          Abstract:        A borehole logging tool employs an energy transmitter and receiver for scanning a borehole with energy pulses.  An orientation pulse is produced each time the tool rotates past a predetermined orientation position.  The time period between orientation pulses is measured and divided into a plurality of discrete intervals.  Sine and cosine functions are generated for the measured time period having a sine and cosine value corresponding to each of the discrete intervals.  The sine and cosine functions are used to produce sweep functions for controlling the outward sweep of the electron beam of a PPI display device so as to produce a circular rotating pattern in which each revolution corresponds in time to a measured time between orientation pulses.  The output of the receiver modulates the electron beam sweep to generate a visual display of the azimuthal scan of the borehole.
