An instrument of an instrument set is used to insert an implant into a disc space. The implant comprises a first cage and a second cage and the instrument comprises a distal end configured to push the cage first inserted into the disc space laterally in its proper anatomical location. Said distal end of the instrument has a tip, which is curved and has a curved inner side configured to contact an outer curved side of the first cage. The instrument set allows the insertion of two cages through a relatively small incision in the interdisc space in a simple jet safe procedure.

The medical implant is constructed of a fiber reinforced plastic. That fibers (50a, 50b) are generally aligned in layers (C, D, E), wherein the fibers of at least two different layers having different orientations. The fibers are long and oriented in relationship to the biomechanical requirements. The implant can oppose multi-directional forces and can be manufactured with the appropriate strength and stiffness.

A device and method for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves makes it possible to measure phase, amplitude and offset of a temporally modulated, spatially coded radiation field. A micro-optical element (41) spatially averages a portion (30) of the scene and equally distributes the averaged intensity on two photo sites (51.1.51.2) close to each other. Adjacent to each of these photo sites (51.1) are two storage areas (54.1, 54.2) into which charge from the photo site can be moved quickly (with a speed of several MHz to several tens or even hundreds of MHz) and accumulated essentially free of noise. This is possible by employing the charge-coupled device (CCD) principle. The device combines a high optical fill factor, insensitivity to offset errors, high sensitivity even with little light, simultaneous data acquisition, small pixel size, and maximum efficiency in use of available signal photons for sinusoidal as well as pulsed radiation signals. The device and method may be used in a time-of-flight (TOF) range imaging system without moving parts, offering 2D or 3D range data.

The present invention relates to a method for detecting the amplitude and/or phase position of an at least partly intensity-modulated signal (PE(t)), and a corresponding device for carrying out the method. In order to provide a method and a device which make it possible to avoid the disadvantages of the start of the art, according to the invention a method and a device for carrying out the method are proposed, the method having the following steps: i) Detecting an instant value of the at least partly intensity-modulated signal (PE(t)), ii) Detecting an instant value of a first reference signal (Um(t)), the first reference signal (Um(t)) having a frequency (ω2) which differs from the frequency (ω1) of the intensity modulation, iii) Mixing the detected instant value of the at least partly intensity-modulated signal (PE(t)) with the detected instant value of the first reference signal (Um(t)) to obtain a mixed-signal value (UΔ), iv) Detecting an instant value of a second reference signal (U1(t)), the second reference signal (U1(t)) having a frequency (Δω) which also differs both from the frequency (ω2) of the first reference signal and from the frequency (ω1) of the intensity modulation, v) Detecting an instant value of a third reference signal (UQ(t)), the third reference signal having the same frequency (Δω) as the second reference signal, but being phase-shifted to the second reference signal (U1(t)), vi) Mixing the mixed-signal value (UΔ) with the detected instant value of the second reference signal (U1(t)) to obtain a first measurement signal value, vii) Mixing the mixed-signal value (UΔ) with the detected instant value of the third reference signal (UQ(t)) to obtain a second measurement signal value, and viii) Calculating the amplitude and/or phase position of the at least partly intensity-modulated signal (PE(t)) from the two measurement signal values.
