Definitions

  • the invention relates to an optical component which combines the properties of a lens with the properties of a reflection prism and is referred to below as a hybrid prism.
  • a prism consists of a base and a top surface as well as a basically unlimited number of side surfaces that connect the base and top surface with one another, so that, for example, a glass cylinder that is optically denser with respect to the surrounding matter can also be referred to as a prism.
  • a reflection prism is used to change the direction of light at two opposing totally reflective boundary surfaces, while a lens has two rotationally symmetrical refractive surfaces, at least one of which is designed so that parallel incident light rays cross at a focal point.
  • the hybrid prism for optical systems with different spectral ranges consists of a rotationally symmetrical body similar to a rotational rhomboid, which is denser than the surrounding matter and has at least one glass body for light with a wavelength of 780 nm to 380 nm and for X-rays with a wavelength of 1 nm to 30 pm a vacuum within an enveloping body that surrounds it on all sides.
  • the rotationally symmetrical body determines the beam path within an optical system over its length in such a way that the beams emanating from an object in a linked beam path enable the object to be depicted on an image surface, whereby they are shown at a front boundary surface in enter the rotationally symmetrical body and pass through an even number of total reflections at two inner boundary surfaces, each of which has an angle of inclination to the optical axis, and exit the rotationally symmetrical body again at a rear boundary surface.
  • At least one of the four boundary surfaces of the rotationally symmetrical body has a generating curve with a continuously changing tangent angle in a longitudinal section.
  • the hybrid prism is designed either as a collecting prism or as a diverging prism or as a condenser prism.
  • the optical system is designed in particular as a human eye with a hybrid intraocular prism or as a lidar system with a headlight or as a projector and generally as an objective for a camera, a telescope or a microscope.
  • the optical system is used as a medical X-ray device and in particular as a tomograph or as a X-ray microscope with a spatial resolution of less than or equal to 20 nm or designed as a terrestrial or satellite-based X-ray telescope.
  • the optical system can be designed for a Petawatt high-energy laser and for X-rays as a fusion reactor, in which a plurality of hybrid prisms are placed on a target are directed at the center of a fusion reactor vessel.
  • Galileo Galilei built a telescope in 1609, the optical system of which consists of a converging lens and a diverging lens, in order to recognize that the sun is not orbiting the earth, but rather the sun is the center of our planetary system.
  • Johannes Kepler combined two converging lenses for his telescope in 1611 in order to observe the orbits of the planets.
  • Antoni van Leeuwenhoek is considered a pioneer of microscopy and built more than 300 microscopes from 1658.
  • Spherical and chromatic aberrations can now be corrected by systems made of several lenses of different types of glass, spherical aberrations by aspherical lenses or gradient lenses.
  • Artificial intraocular lenses are designed to correct ametropia in the human eye. In the case of end-stage macular degeneration, this has hardly been possible so far.
  • macular degeneration AMD is the most common cause of severe visual impairment and affects 20% of the 65 to 74 year olds and 35% of the 75 to 84 year olds. End-stage AMD affects around 5% of 75 to 84 year olds.
  • Lidar is the English abbreviation for (light detection and ranging) and, like the term Ladar (laser detection and ranging), stands for a method related to radar in which laser beams are not used for detection and distance measurement, as is the case with radar used by objects. This technology plays a key role in the announced autonomous movement of vehicles, which is already taking place with restrictions.
  • a lidar system which is also used as a dipped beam headlamp, is a desirable option for vehicle occupants, whether they are being driven or driving themselves. It has been known for more than 100 years that X-rays, unlike visible light, can penetrate substances such as skin, tissue, fascia, muscles, tendons, ligaments and bones. From the vacuum tube used by Conrad Röntgen and the associated simple projection method, the X-ray devices that are still used today quickly developed as versatile medical diagnostic instruments that create an image on an exposed film by simple projection.
  • a monochromatic X-ray beam with a diameter of approximately 1 mm and which is coupled out from a synchrotron can be focused by means of a large number of lenses in order to generate an image of an object being irradiated.
  • the disadvantage of this is the fact that very much Many such lenses have to be arranged one behind the other on an optical axis in order to achieve the desired focusing.
  • mirrors made of multiple layers for the grazing incidence of radiation, X-ray grids and X-ray lenses are available for X-ray analysis processes in order to achieve a high spatial resolution in X-ray analysis, which was not possible with the previously known X-ray diagnostics as a simple projection of the divergent X-rays onto a screen.
  • the current state of the art always requires two optical systems to first condense the monochromatized X-ray radiation, then to X-ray an object and then to generate an image on an image surface using an X-ray objective and a detector.
  • the x-rays are condensed by means of a zone plate and a pinhole, the zero-order x-rays are masked out by a radiopaque diaphragm, so that only an incomplete image of the object can be generated by means of a hollow cone-shaped divergent beam.
  • a condenser optic For focusing a monochromatic parallel beam, a condenser optic is provided, which is formed, for example, by a refocusing mirror or a zone plate condenser and first concentrates the parallel beam on a focus of the condenser, in order to then introduce a divergent beam into a capillary optic, which is formed, for example, by a paraboloid of revolution will. Since the paraboloid of revolution cannot reflect the central rays of a divergent or parallel bundle of rays, this defect is transmitted via the X-ray lens to the CCD sensor of a camera.
  • X-ray microscopy is associated with the difficulty of having to arrange the object to be examined in the focal point or in the immediate vicinity of the focal point or to choose an offset solution in order to be able to record an image on the image surface of the detector.
  • X-ray microscopy is subject to a number of methodological constraints that severely limit the arrangement of the components of the optical system and the size and arrangement of the object to be examined.
  • Another possible application for the hybrid prism according to the invention is nuclear fusion. In order to be able to realize nuclear fusion, the so-called Coulomb force must first be overcome, with which positively charged atomic nuclei repel each other.
  • a so-called tocomak is designed to guide electrons and protons along the magnetic field lines of a magnetic field on helical paths. This requires strong magnetic coils in a radial and concentric arrangement around a toroidal fusion container.
  • the so-called inertial confinement a target in the center of a spherical reaction container is bombarded with laser or particle radiation, so that the fusion temperature is reached very quickly and numerous fusion reactions have already taken place before there is enough time and space for the expansion of the plasma was standing.
  • the problem with smaller Tokomak-type fusion reactors is the very short energy containment time, since the plasma cools down faster than expected.
  • the internal turbulence of the plasma is responsible for the cooling, which, comparable to the regularly occurring solar flares, transports large amounts of energy from the hot core of the sun to the surface.

  • the hybrid condenser prism 14 corresponds to the exemplary embodiment described in FIGS. 18 and 19.
  • the X-rays R have a radiation source Q (not shown in more detail), which corresponds to the exemplary embodiment shown in FIG. 23 and comprises a synchrotron 210 and an undulator 211.
  • the divergent bundles of rays SD of the plurality of hybrid condenser prisms 14 heat the plasma 301, in particular in the less hot area of the plasma 301 facing the inner wall of the pressure vessel 302.
  • energy is supplied to the plasma 301 during the fusion, so that the temperature gradient between the hot core and the relatively cooler edge areas is reduced.
  • the peripheral fusion of the plasma 301 takes place by ionizing as many particles as possible.
  • the heat potential of the plasma 301 has so far only been partially used, since the plasma formation already takes place when every ten thousandth particle is ionized.
  • the smearing of the plasma 301 by means of X-rays R enables a more uniform heat distribution in the plasma 301, so that the formation of undesired turbulent flows in the plasma 301 can be avoided. If it is possible to extend the energy containment time, a comparatively small calibrated fusion reactor can also be operated with a considerable excess of energy.
  • FIG. 26 shows the exemplary arrangement of four hybrid condenser prisms 14 for X-rays R, which correspond in their geometric structure to the exemplary embodiments shown in FIGS. 18 and 19, with a radiation source Q which corresponds to the exemplary embodiment shown in FIG. 23.
  • the common focal point Fd of the hybrid condenser prisms 14 is im Center of the pressure vessel 302 of a fusion reactor 30, which works on the principle of inertial fusion, arranged. Both the space surrounding the pressure vessel 302 and the space enclosed by the pressure vessel 302 have a vacuum V.
  • a spherical hydrogen capsule 300 is arranged concentrically to the common focal point Fd of the hybrid condenser prisms 14, the outer shell of which consists of a metal foil, for example silver, and which contains the heavy isotopes deuterium and tritium of hydrogen as fuel for the fusion reactor 30.
  • At least two or a plurality of hybrid condenser prisms 14 can be arranged on the pressure vessel 302.
  • FIG. 27 shows a plurality of hybrid condenser prisms 14, at the front boundary surfaces a of which a Petawatt flare energy laser enters the hybrid condenser prisms 14, is totally reflected at the inner boundary surfaces b, c, and is focused on focal points Fd at the rear boundary surfaces d.
  • the hybrid condenser prism 14 can be made of glass, for example, and has a two-part enveloping body 11 with a front and a rear correction lens 110 and the interfaces a and d, as well as a spindle 111 arranged concentrically to the optical axis x with the interface b and a die
  • the focal point Fd can have a diameter> 5 nm, a very high energy density is available at the focal point Fd, which is sufficient for this on the outside of a hydrogen capsule 300, which is surrounded by a metal foil, extending into the interior of the hydrogen capsule 300 causing a propagating shock wave, so that inside the hydrogen capsule 300 a plasma 301 spreads from the outside to the inside and a nuclear fusion of the heavy isotopes of hydrogen, deuterium and tritium, can be triggered very quickly. Since the expansion of the plasma 301 proceeds more slowly than the nuclear fusion itself, an extended energy containment time is possible, so that the fusion process can achieve an energy surplus.
  • Water is a suitable heat transfer fluid in order to derive the heat energy obtained from the fusion reactor 30 and to convert it into electricity, for example, in a steam turbine with a connected generator.
  • the optical systems 2 shown in FIGS. 26 and 27 it is possible to achieve a resonance effect by means of shock waves propagating in opposite directions, all particles of the plasma 301 being ionized and the temperature of the plasma 301 rising over a longer period of time.
  • the extended energy containment time again leads to an excess of energy from the nuclear fusion.
