Abstract:
A waveform scan system, comprising:a) means for producing two pairs of special waves and its special waveforms contain the pulse portion and the long length intermittence portion, said two pairs of special waves used to form two special stationary waveform in which contains a maximum peak area;b) a two dimensional electrically-conducting media in which contains three layers that overlay one on front of each others, the front layer of said three layers of material in which said special stationary waveform can be formed, the middle layer of said three layers of material reactive with electric power or reactive with incoming power in which the image signals can be display or be handled for further process and reactively means it characters will be changed under certain strength electrically-power or incoming power, the rear layer of said three layers of material in which said special stationary waveform can be formed;c) a control unit by which to change said intermittence length of said special waves, or to change the phase of said special waves, or to change both said intermittence length and said phase of said special waves whereby the movement of said maximum peak lines can be controlled whereby said scan system achieves synchronism with outside signal, or achieve to other purpose;d) said one pair of special waves are led to two sides of said front layer of said media and spread in it at opposite directions to form said special stationary waveform that contains a maximum vertical peak line area, said anther pair of special waves are led to top and bottom sides of said rear layer of said media and spread in it at opposite directions to form said special stationary waveform that contains a horizontal maximum peak line area, said vertical and horizontal maximum peak lines cross in space and their perpendicular line presents a maximum peak point value, while said vertical maximum peak line said horizontal maximum peak line move by said control unit, said maximum peak point scans whole said two dimensional electrically-conducting media whereby the said peak point works as trigger.
