    摘要: A device for the deflection of a laser beam for optical measuring systems comprises an optical element (11) for the deflection of an incident laser beam and a drive unit for the generation of a rotational movement between the optical element (11) and the incident laser beam, in order to deflect the laser beam in a series of differing directions. The optical element (11) comprises at leas two segments (12a, 12b) for the deflection of the incident laser beam, each by a fixed deflection angle. The laser beam is sequentially incident on the differing segments (12a, 12b) with the rotational movement. The optical element (11) is embodied as a disc or ring and the segments are cuneiform with inclined surfaces. In a method for laser beam deflection, an incident laser beam which is offset from the rotation axis (A), is deflected in a precisely defined direction for a duration (t) by each segment (12a, 12b).

    摘要: An optical switch is disclosed having 4-ports. The switch consists of a first GRIN lens having 2 ports (1 and 3) adjacent its outwardly facing end face, on opposite sides of an optical axis of the lens. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports (2 and 4) adjacent its outer end face, on opposite sides of an optical axis. In a first state, a first port (1) from the first GRIN lens couples light with port (2) of the second GRIN lens, and a second port (3) of the first GRIN lens simultaneously couples light with another port (4) of the second GRIN lens. A movable optical element, that when disposed in the path between first and second GRIN lens, provides only a single connection between a port of the first GRIN lens (1) and a port of the second GRIN lens (4) while preventing light from coupling between the other two ports (2 and 3). Hence a 1 ½ x 2 optical switch is disclosed. Furthermore, the optical switch is disclosed having multiple input and output ports. The switch consists of a first GRIN lens having 2 ports adjacent its outwardly facing end face. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports adjacent its outer end face. In a first state, a first port from the first GRIN lens couples light with a first output port of the second GRIN lens. In a second state, a movable optical element in the form of a light transmissive wedge having a reflective surface, is disposed in the path between first and second GRIN lens, providing a connection between a port of the first GRIN lens and a second port of the second GRIN lens. In a third connect state, the reflective surface of the wedge connects a port of the first GRIN lens and an output port in the same first GRIN lens. Hence an N x M optical switch is disclosed.

    摘要: An interferometer is disclosed that is used with a frequency shifting phase conjugate mirror (PCM) (12), to produce a 90° polarization rotation, and employs only two adjustable elements: a specially shaped prism (16), and a beam deflector that is preferably a porro prism (40). The primary prism is shaped and oriented so that a linearally polarized input beam (4) is divided into ordinary (o) and extraordinary (e) subbeams (24, 26). One of the subbeams (26) is refracted out of the prism along a controlled length path, and then returned back into the prism by the deflector (40). The second subbeam (24) is retained within the prism by total internal reflection, and directed onto an exit path (38) that coincides with the path of the first subbeam (26) after its reentry into the prism (16). The recombined output beam (10) is directed into the PCM (12), from which it is reflected back into the prism (16) for a reverse pass. The difference in path lengths between the o and e subbeams is selected to produce a net 90° polarization rotation after both passes.

    摘要: The high spatial resolution area array detection readhead and method for using the same involve modifying an existing area array detection readhead to provide improved spatial resolution within the sample detection area. One modification involves reducing the field of view of the area array detection readhead. The reduction in the field of view increases pixel spatial resolution because the same number of pixels in the area array detector cover a smaller area. This reduction can be achieved by changing the magnification of the lens of the area array detection readhead or by moving the sample detection area closer to the area array detection readhead. The next modification involves properly aligning the reduced field of view within the sample detection area to take advantage of the improved pixel resolution. Preferably, by rotating the typical area array detection readhead 90 degrees with respect to the sample detection area, the length of the reduced field of view aligns with the width of the sample detection area. Finally, an optical wedge is positioned between the area array detection readhead and the sample detection area. The optical wedge is designed to shift the reduced field of view a predetermined number, X, of degrees from normal along the length of the sample detection area to cover a first field of the sample detection area. By inverting the optical wedge or introducing another optical wedge, the field of view is shifted -X degrees from normal and fills the remaining field of the sample detection area. As such, the sample detection area is divided into two fields that cover the entire sample detection area. Accordingly, by switching the optical wedge between the two wedge positions, the improved area array detection readhead shifts the reduced field of view + and - X degrees to image the entire sample detection area at the higher spatial resolution.

    摘要: Catadioptric optical systems are generally arranged to view a fixed large field of view. Apparatus for steering a field of view includes a pair of Risley prisms (15, 16), which are disc shaped prisms having a generally shallow wedge like side cross-section, arranged in the path of the incoming radiation. The prisms are rotatable with respect to each other and to the optical axis of the system so as to steer the field of view.
    By utilising such steering in a dual waveband system then a system having two fields of view and two magnifications may be achieved in which an image over a smaller field of view but of high magnification may be steered within a larger image of large field of view but low magnification.

    摘要: For monitoring and controlling a laser beam, sample beams are monitored for three characteristics and the three monitor outputs are used to control the beam generation. The three characteristics monitored are the transverse distribution of energy within the beam (a) under far field conditions and (b) under near field conditions, and (c) total power within a known proportion of the beam. These are employed respectively to control (a) the position of a mirror which forms part of an optical cavity within the laser structure, (b) a beam pointing element, (c) a beam expander and (d) a power supply for the laser.
