Abstract: The claimed invention relates to an adjustable derivative contract. Particularly a method and system for adjusting the derivative contract to account for time value of money due to an occurrence of a corporate event that affects the value of the derivative contract. The claimed method and system allocates distributions amongst different derivative contracts, each derivative contract representing a different economic interest of at least two shares of an underlying security. The claimed invention uses the concepts of present and future values to value derivative contracts in order to more fairly and accurately represent the interests of the various holders of such derivative contracts upon the occurrence of a corporate event affecting the value of these derivative contracts.

Abstract: Apparatus for indicating the departure of a shape of an object (3;11;16;18;22;26) from a specified shape is described. The apparatus comprises radiation means for directing an incident beam of radiation (4) onto the object, and inspecting means (5) for inspecting the final beam after transmission by or reflection from said object. The apparatus is arranged so that the final beam will have a substantially planar wavefront when said object has said specified shape, and said inspecting means (5) is arranged to determine any departure of the wavefront of the final beam from planarity. In one embodiment, the inspecting means comprises beamsplitting means, for example a diffraction grating (6) or hologram, and detector means such as a CCD camera (8). The beamsplitting means is then arranged to split the final beam into two or more beams and to direct said two or more beams to laterally displaced locations on the detector means.

Abstract: Optical apparatus for simultaneously focussing first and second coaxially spaced object planes in respective separate first and second areas of a common image plane 13 (such as the sensor of a CCD camera) comprises non-diffractive beamsplitter means for receiving light from said object planes along a common path 2 for transmission to said first and second image areas along respective first and second optical paths 3, 4, and reflective or transmissive focussing means 8 arranged to bring said first and second object planes into focus in said first and second areas. The object planes may be differentiated by having different length paths 3,4 (different physical lengths and/or using a differential optical delay), and/or by having different focussing powers in the two paths. In an add-on for a camera, differently curved mirrors of long focal length modify the main camera lens. Polarising optics may be used to separate the two images. The apparatus may be used for 3-D imaging or wavefront analysis.

Abstract: A multi-pass optical amplifier system is provided comprising an amplifier medium (20) and at least one relay imaging telescope (18, 24) for imaging light from the amplifier medium onto a primary light directing optical component, such as a mirror (26, 29) and for imaging light directed back from a primary light directing optical component (26, 28) into the amplifier medium so that light is re-passed through the amplifier medium. The system further includes a phase conjugate mirror arrangement for intercepting light between passes for the amplifier medium to generate a phase conjugate reflection of the light incident on it. Preferably, the system is arranged such that a light beam is incident on phase conjugate mirror (22), after having passed through the amplifier medium a predetermined number of times and the phase conjugate reflection retraces the path of the incident beam.

Abstract: An optical beam steering device (10) incorporates a laser (12), three Brillouin shifters (22 to 26, 44 to 48, 54 to 58), a four wave mixing cell (40) and a low power beam steering device (62). The first shifter (22 to 26) and the mixing cell (40) contain TiCl.sub.4, and the other shifters (44 to 48, 54 to 58) contain 20% CCl.sub.4 /80% CS.sub.2. The first and third shifters (22 to 26, 54 to 58) frequency downshift the laser beam (16) by .delta..upsilon..sub.A and .delta..upsilon..sub.B respectively. Light (16') from the first shifter (22 to 26) is amplified and provides a first pump beam input to the mixing cell (40). It then passes to the second shifter (44 to 48), for frequency downshifting by .delta..upsilon..sub.B and returns as a second cell pump beam ( 16"). Light (18') from the third shifter (54 to 58) passes via the low power beam steering device (62) to the cell (40) as a weak input signal beam (18").
