摘要： A continuously variable ratio beam splitter and beam launcher for dividing an input light beam, particularly a polarized coherent light beam, into two output beams, within a broad intensity variation range between the beams which may approach zero to 100%, without loss of polarization, comprises an optical array on a support adjustably mounted on a frame; the optical array includes an optical divider aligned with a penta prism that effectively couples the optical divider to one side surface of a right angle output prism. The optical divider and the output prism launch two output beams, based on division of the light from the input beam impinging on the optical divider. Variation of the intensity ratio of the output beams is accomplished by rotating the optical array support about a pivot point aligned with the input beam so that the input beam strikes the optical divider at different angles. Each output beam is picked up by an optical fiber or like transmission element previously located at a fixed position on the frame of the device. The output beams are always aligned along essentially the same output paths, regardless of changes in the angular orientation of the optical array, so that the amplitude ratio between the two output beams can be changed merely by rotational adjustment of the optical array without refocusing or adjusting other components of the device.

摘要： A positioner for accurately and precisely positioning an optical member such as a lens aligned with the tip of an optical fiber in relation to an optical device such as a beam launcher/splitter; the positioner includes a tilt base mounted in a frame and angularly displaceable about orthagonal X and Y axes defined by three ball bearings all engaging one surface of the tilt base and all biased against the tilt base. Two differential screws mounted on the frame engage two of the ball bearings to effect angular yaw and pitch adjustments. The tilt base is connected to a retainer support in turn connected to a retainer member; two additional differential screws engage the support through further ball bearings to effect linear movements of the retainer member along the X and Y axes. The retainer member includes a lens and an adapter aligned along the Z axis with an optical fiber cable whose tip is releasably connected to the adapter; the adapter has an internal flange that accurately locates the tip of the optical fiber at the focal point of the lens.

摘要： A continuously variable ratio beam splitter for dividing an initial p-polarized coherent light beam into two polarized output beams, with a range variation of zero to 100%, comprises an optical array including a right angle input prism facing a first right angle output prism along their hypotenuses and a penta prism coupling one side surface of the input prism to a side surface of a second right angle output prism; the two output prisms produce the output beams by division of light from an input beam impinging on the other side surface of the input prism. Variation of the intensity ratio of the output beams is accomplished by rotating the array so that the input light beam strikes the hypotenuse surface of the input prism between the critical angle and the Brewster angle for that prism surface. Simple one-spring positioner devices hold two fiber optic cables with the fiber ends at the foci of two lenses used to collect the output beams; those positioners provide rotational adjustment to preserve uniform polarization in the light outputs from the optical fibers. A device for demonstrating interference effects, comprising two simple attachments for the distal ends of the fiber optic cables, is also disclosed.

摘要： A pressure displacement dredging system capable of effective and efficient operation, without surging, over a wide depth range and under varying bottom conditions, comprises a submersible dredging head including at least three pressure vessels each having a material intake port and a material discharge port with appropriate check valves, each having an inlet port for air or other operating fluid connected to a high pressure fluid source through an inlet valve and each having an operating fluid exhaust port vented to the atmosphere through an exhaust valve. The system provides cycle control means, actuated by low level sensors in each pressure vessel, which actuates the vessels between discharge and filling phases in a predetermined closed sequence; when the level of material in a first discharging vessel drops below the low level sensor the cycle control opens the inlet valve and closes the exhaust valve for the next vessel in the sequence to initiate pressure displacement discharge of material from that next vessel, and thereafter closes the inlet valve and opens the exhaust valve of the first vessel so that the first vessel fills by pressure displacement, the sequence being such that each pressure vessel is full before discharge of that vessel is initiated. One modification of the system provides a vacuum assist for dredging in extremely shallow conditions.
