摘要： The present invention relates to the communication or reproduction of sound, in particular audible sound. There is provided a method of communicating a sound, including the steps of: transmitting, onto an optical link, pairs of signal copies, the signal copies of a given pair having a time offset relative to one another; applying the audible sound to the optical link, such that the audible sound causes a phase modulation to the transmitted signal copies; receiving modulated signal copies previously transmitted onto the link; and, for received pairs of signal copies, causing one signal copy of a pair to mix with the other signal copy of that pair so as to produce a signal representative of the sound. The sound is an audible sound. It has been found that a delay of at least 75 micro seconds allows for a better reproduction of audio sounds, since these have a relatively low frequency content.

摘要： A bidirectional optical space switch for selectively coupling an input signal to a selected output comprises two arrays of inputs (1, 8), two arrays of outputs (5, 9), polarizing beam splitters (2, 4), and a matrix of cells (3) each of which is selectively capable of varying the polarization state of light passing through it in response to an applied control signal. A first optical system (6) couples each of inputs (1) and a corresponding one of outputs (9) with a corresponding column of cells while a second optical system (7) couples each of inputs (8) and a corresponding one of outputs (5) with a corresponding row of cells. One of inputs (1) is switched to one of outputs (5) by activating the appropriate cell so that it rotates the polarization of light passing through it by 90.degree.. This also couples one of inputs (8) to one of outputs (9) thereby providing bidirectional switching. Use of combined beam splitters and polarizers (2, 4) provides bidirectionally at substantially no loss of light additional to that lost on discrimination of the polarization states.
