A personnel monitoring system. The personnel monitoring system includes a host node having an optical source for generating optical signals, and an optical receiver. The personnel monitoring system also includes a plurality of fiber optic sensors for converting at least one of vibrational and acoustical energy to optical intensity information, each of the fiber optic sensors having: (1) at least one length of optical fiber configured to sense at least one of vibrational and acoustical energy; (2) a reflector at an end of the at least one length of optical fiber; and (3) a field node for receiving optical signals from the host node, the field node transmitting optical signals along the at least one length of optical fiber, receiving optical signals back from the at least one length of optical fiber, and transmitting optical signals to the optical receiver of the host node.

A light powered communications system. The light powered communications system includes an audio control center having at least one optical source and at least one optical receiver. The light powered communications system also includes a plurality of optically powered remote communication systems located remote from the audio control center, each of the optically powered remote communication systems being configured to receive an optical signal from the audio control center. The light powered communication system also includes at least one length of fiber optic cable between the audio control center and each of the optically powered remote communication systems.

An optical microphone includes a vibrating membrane defining a diaphragm for receiving acoustic signals. An optical element such as a lens is attached for vibrating with the membrane in direct relationship with the acoustic input signals. Fixed fiber optic cables may be placed in alignment with the lens for directing the initial light toward the lens and transmit the directed light from the lens. A single or dual fiber optic geometry may be used with the vibrating lens.

A Tandem Scanning Microscope is disclosed using a modified Nipkow disk design. With this scanning system, scanning is performed using many apertures at once and using one disk for both image and illumination scanning. The apertures in the disk are in an annular pattern of spiral arms. Each aperture is located along a spiral arm at the end of a radius vector. Relative aperture locations are established in accordance with a mathematical relationship.
