Abstract: A bypass for an optical fiber ring network, including a first partially reflective and partially transmissive surface and a second substantially reflective surface located behind the first surface. Each node of the network includes a transmitting device and a receiving device, each of which is served by an optical fiber. There is also an incoming fiber that supplies signals from the network and an outgoing fiber that is used to place signals on the network. With this invention, the transmitting, incoming, receiving, and outgoing fibers are arranged such that the signal from the transmitting fiber is reflected off the first surface onto the outgoing fiber. The signal from the incoming fiber is reflected off the first surface onto the receiving fiber and also reflected from the second surface onto the outgoing fiber. This feature allows incoming signals to be both received at the node and also passed onto the next node of the ring, which is especially important when the node is inoperable.

Abstract: A hardware packaging assembly for a galvanometer optical beam scanning apparatus includes an optical component-containing portion having a light source aperture through which the output beam from the ILD that carries the to be recorded data passes. This aperture is disposed in a wall defining a boundary of the interior of the housing. Light from the ILD is reflected off a fixed mirror disposed adjacent to an opposite wall and is directed to a galvanometer scanning mirror. As the mirror is rotated about a longitudinal axis, it scans the ILD output beam across an output (image correction) lens mounted in the housing. A second opening disposed in the rear wall of the housing interior receives a start-of-scan photodetector element, which is positioned to detect light that is back-reflected off the inner face of the lens at a prescribed angle of sweep of the beam by the galvanometer mirror.

Abstract: A wavelength division multiplexed fiber-optic communication system employs a pair of terminal stations, at opposite ends of the fiber-optic link, with the base configuration of each terminal station being the same. In each station a selective coupling arrangement is provided between the source or transmitter devices as well as the receiver devices and the single optical fiber over which the transmission are to take place so as to effectively make the terminals interchangeable. For achieving this purpose, each terminal station is comprised of a transmitter or source arrangement that is capable of generating a plurality of wavelengths. Similarly, each terminal station includes a receiver or detector which is capable of detecting the plurality of wavelengths that are selectively available for transmission or generated by the transmitter or source.

Abstract: A high resolution scanning system, employing non-linearly driven galvanometer deflection optics, compensates for both the non-linear rate of travel of the information pixel beam and for pixel position offset introduced by an optical subsystem (a flat field lens) that equalize pixel size and quality across the recording medium. The system employs a single high speed reference clock the output pulses of which are counted and used to address a compensation data-containing PROM (programmable read only memory). The contents of successive addresses of the PROM contain pixel location codes identifying the position on the recording medium where a pixel of interest is to be recorded. These codes are derived in accordance with the periodic non-linear rate of travel of the scanning optics across the recording medium and the measured parameters of a flat field lens disposed in the path of the scanning beam.
