原文:
Every lighthouse has a distinctive pattern of light known as its
characteristic. There are five basic characteristics: fixed, flashing,
occulting, group flashing, and group occulting. A fixed signal is a steady
beam. A flashing signal has periods of darkness longer than periods of light,
while an occulting signal’s periods of light are longer. A group-flashing
light gives off two or more flashes at regular intervals, and a
group-occulting signal consists of a fixed light with two or more periods of
darkness at regular intervals.Some lighthouses use lights of different colors
as well, and today, most lighthouses are also equipped with radio beacons.
The three types of apparatus used to produce the signals are the catoptric,
in which metal is used to reflect the light; the dioptric, in which glass is
used; and the catadioptric, in which both glass and metal are used.
