    摘要： An optical fiber link card communication module, and process for fabricating the module, where the module provides a parallel electrical interface to the user, facilitates high speed serial transmission of data over an optical data link, and contains a plurality of converters (130,131) for performing conversions between both electrical and optical signals. The module further includes edge mounted optical components having leads mounted on the surface of a card (as opposed to standard pin-in-hole type leads) to minimize lead capacitance and inductance from the optical components to the card electronics, on board card control means for the converters and safety shut down means on the same card as the electrical and optical components. A preferred embodiment of the invention contemplates fabricating the optical communication module on a single multilayer card with all the transmitter electrical components being located on one side of the card, all receiver electrical components being located on the other side of the card, and the transmitter and receiver components being separated by shielding layers in the card. By using two transmitter/receiver pairs (with the transmitters and receivers being located on respective sides of the card) an embodiment of the invention provides for double full duplex communications.

    摘要： A fully redundant safety interlock system is provided comprising, means for detecting the loss of light on a fiber optic link; controller means, coupled to said means for detecting, for determining the safety condition of the link based on the output of said means for detecting, and for controlling the radiant energy output of an optical transmitter, based on the determined safety condition, via redundant output control signals; and means, coupled to said controller means, responsive to said redundant control signals, for interconnecting the output of said controller means to transmitter drive circuitry to thereby adjust the radiant energy output by the transmitter. According to a preferred embodiment of the invention, the controller means includes an electronic implementation of two independent state machines, each of which redundantly determines the connection state of the optical link between two optical link cards. The output from the state machines is used to adjust (for example, turn on and turn off) the drive circuitry for the transmitter via fully redundant paths which carry the redundant control signals.

    摘要： An optical serial data bus for connecting logic cards (15) used in a data processing system. The bus uses semicon­ductor lasers (21) and PIN diodes (20) as transmitters and receivers, transmitting through free space without the use of lenses or other optical elements. Each logic card communi­cates only with the adjacent cards on either side to minimize the transmission distance.

    摘要： In this system the light reflected back over the path (10a) to be measured is fed directly into a semiconductor laser (8a). As is commonly known, the introduction of reflected power through the front, or emitting, facet of the laser actually alters the power present in the laser with an attendant effect on the signal from a photosensor (15) usually located on the rear facet of the laser. The output signal from the photosensor associated with the laser has an asymmetric sawtooth (triangular) waveform. This is in contrast to the output signal from a conventional interferometer which has a sinusoidal waveform.
    The photosensor output signal is profoundly affected by the return beam. Also unexpectedly, the sawtooth output signal from the photosensor is an essentially linear signal over the range between adjacent fringes. That is, except for the transition at positive and negative peaks. As the path length (10a) of the reflected beam is increased or decreased, the sawtooth output signal changes in a direct linear relationship to the change in path length. This allows precise measurement of changes in distance less than the distance between adjacent fringes.

    摘要翻译： 在该系统中，将被测量的路径（10a）反射回的光被直接馈送到半导体激光器（8a）中。 众所周知，通过激光器的前面或发射面引入反射光，实际上改变了激光器中存在的功率，对来自光电传感器（15）的信号具有附加的作用，通常位于激光器的后面 激光。 来自与激光器相关联的光电传感器的输出信号具有不对称的锯齿波（三角波形）波形。 这与来自具有正弦波形的常规干涉仪的输出信号相反。 光电传感器输出信号受到返回光束的深刻影响。 也令人惊讶的是，来自光电传感器的锯齿波输出信号是相邻条纹之间的范围上的基本线性信号。 也就是说，除了在正和负峰值的过渡之外。 当反射光束的路径长度（10a）增加或减小时，锯齿波输出信号与路径长度的变化呈直线关系。 这允许精确测量距离小于相邻条纹之间的距离的变化。
