Apparatus for obtaining information for a structure using spectrally-encoded endoscopy teachniques and methods for producing one or more optical arrangements

Exemplary apparatus for obtaining information for a structure can be provided. For example, the exemplary apparatus can include at least one first optical fiber arrangement which is configured to transceive at least one first electromagnetic radiation, and can include at least one fiber. The exemplary apparatus can also include at least one second focusing arrangement in optical communication with the optical fiber arrangement. The second arrangement can be configured to focus and provide there through the first electromagnetic radiation. Further, the exemplary apparatus can include at least one third dispersive arrangement which is configured to receive a particular radiation which is the first electromagnetic radiation and/or the focused electromagnetic radiation, and forward a dispersed radiation thereof to at least one section of the structure. At least one end of the fiber can be directly connected to the second focusing arrangement and/or the third dispersive arrangement. In addition, an exemplary embodiment of a method for producing an optical arrangement can be provided. For example, a first set of optical elements having a first size in a first configuration and a second set of optical elements in cooperation with the second set and having a second size in a second configuration can be provided. The first and second sets can be clamped into a third set of optical elements. The third set can be polished, and a further set of optical elements may be deposited on the polished set.

High-speed, hand-held reciprocating method for cutting, carving, sawing, chiseling, filing, sanding, and engraving

A high-speed, hand-held attachment for flex rotor shafts of power rotary tools, and also for direct attachment to power rotary tools without flex rotor shafts, that converts rotary motion to reciprocating motion for precision control of cutting, carving, sawing, chiseling, filing, sanding, and engraving on delicate work pieces. The attachment is one assembly comprising a one-piece front one-piece enclosure (20), a rear one-piece enclosure (30), a high-speed bearing (22), a one-piece rotating piece (40) with integral cam groove, a one-piece reciprocating piece (50) with an integral cam follower on one end and with its other, exposed end accomodating the attachment of a chuck or collet and with geometry to prevent rotation, and a thumbscrew (32). Rotating piece (40) attaches directly to the rotary power source and provides the cam action drive to reciprocating piece (50). Bearing (22) provides rotative support for the other end of rotating piece (40). Reciprocating piece (50) slidably mounts in front one-piece enclosure (20). Front one-piece enclosure (20) and rear one-piece enclosure (30) are attached to each other and maintain proper alignment for rotating piece (40), bearing (22), and reciprocating piece (50). Thumbscrew (32) secures the attachment to the flex rotor shaft of a power rotary tool. A tool holder / collet is attached to the exposed end of reciprocating piece (50) whereby numerous types of cutting tools may be utilized. Alternative versions of the rear one-piece enclosure, (30A) and (30B), described herein, allow for attachment directly to power rotary tools without flex rotor shafts. Alternative versions of the reciprocating piece, (50A), (50B), and (50C), and of the rotating piece, (40A), are also described herein.

Automatic grinding and polishing system for crystal blanks

The invention discloses an automatic grinding and polishing system for crystal blanks. The automatic grinding and polishing system comprises a first left-right transfer mechanism and a second left-right transfer mechanism, feeding and discharging stations, a plurality of upper hemispherical grinding and polishing stations and butting stations are sequentially arranged from left to right along the first left-right transfer mechanism, butting stations, a plurality of lower hemispherical grinding and polishing stations and feeding and discharging stations are sequentially arranged from right to left along the second left-right transfer mechanism, feeding and discharging machines are arranged on the feeding and discharging stations, grinding and polishing machines are arranged on the grinding and polishing stations, butting machines are arranged on the butting stations, each left-right transfer mechanism comprises a plurality of transfer manipulators and a rail linearly extending left and right, the feeding and discharging machines, the grinding and polishing machines and clamp holders for mounting clamps on the butting machines are arranged in a left-right rowed manner along the length direction of the clamps, and the transfer manipulators push the clamps to slide between the left-right adjacent clamp holders along the length direction of the clamps. By the aid of the technical scheme, the automatic grinding and polishing system is more reasonable in structure, simpler in action, lower in cost, more reliable in operation and higher in efficiency.
