Patent DE-19617637-A1 (DE)
Title: Free electron laser appts.
Inventor: STOCK STEFAN DIPL PHYS
IPC: H01S3/09
Filed: 1996-05-03
Abstract: The free electron laser or device for generating electromagnetic radiation uses an electron beam. The electron beam is accelerated by magnetic force. The device uses a current passing grating (1-4) in the beam path or near the beam path of the electron beam. This generates a magnetic field with adjustable amplitude and alternating direction. In the preferred arrangement,the device has four gratings (1-4) each with four grating rods. The current direction alternates in successive gratings. The electron beam (5) is shifted along the middle axis and is deflected and moved to and fro by the magnetic field. The magnetic fields of the individual lines are superimposed and at a distance from the gratings the magnetic field is relatively uniform.

Patent DE-19624802-A1 (DE)
Inventor: FORSSMANN WOLF-GEORG PROF DR M
IPC: G01N33/68
Filed: 1996-06-21
Abstract: The invention relates to a rapid process for medical and diagnostic, qualitative and quantitative protein analysis of the exchange of individual amino acids with pathogenic or non-pathogenic effects on the organism. The medical and diagnostic analysis is achieved by combination of enzymatic or chemical separation of the isolated peptide, chromatographic separation of the fragments and analysis by mass spectrometry, and of direct liquid chromatography-mass spectrometry (LC/MS) and indirect matrix-assisted laser desorption ionisation mass spectrometry (MALDI-MS), and analysis by capillary electrophoresis. By comparing the protein samples of healthy people with the samples of sick people, said process can be used to determine novel, presently unknown mutations, and to quantify the expression and incorporation of a wild type to form a mutant.

Patent DE-19637131-A1 (DE)
Inventor: BECKER MICHAEL DR
IPC: G01N21/55
Filed: 1996-09-12
Abstract: The invention concerns an arrangement for assessing the reflection behaviour of an object (14), in particular an electro-optical display element, said arrangement displaying the conoscopically generated two-dimensional (flat) intensity distribution of reflection radiation on a two-dimensional detector array (17), said radiation resulting from a test beam (15) which is coupled in via the collimating lens (20) of precisely this conoscopic system (19). The position of the test beam in the rear (image side) focal plane of the collimating lens determines the angle and plane of incidence. The test beam is produced, for example in the collimated state, from a divergent source beam (23) fed directly into the focal plane on the image side. However, in order to be able in particular to measure and assess the reflection properties of display elements and their components even when illuminated in a quasi-diffuse manner, a collimated source beam is deflected via ultimately non-polarizing beam dividers in the direction of the optical axis of the lens system and is shaped to form a beam which converges at the front focus. The diameter of this source beam can be used to set a divergence of the test beam which resembles the diffuse irradiation. In this way, the reflection behaviour of electro-optical displays can be rapidly, reproducibly and quantitatively determined without direct mechanical direction scanning (or angle scanning) of the hemisphere for all the irradiation directions and types concerned (ranging from the directed to the diffuse) with white light or light adapted spectrally to the actual situation.

Patent DE-19707225-A1 (DE)
Inventor: WULF JUERGEN DR
IPC: G01N21/88
Filed: 1997-02-24
Abstract: The invention relates to a light-scanning device for exciting and detecting secondary light, especially fluorescent light, on a sample, comprising a light-emitting device to emit exciting light with a suitable wavelength for exciting secondary light on or in said sample, a scanning unit for scanning at least one sub-area of said sample with said exciting light, and a sensing unit for the secondary light emitted when said sample is excited, with a collecting lens and a detecting device. When non-local resolution point detectors are used, the detector must be read and reinitialized every time any scanning spot on the sample has been lit. This requires a waiting period before the scanning ray can be used further. The inventive device uses a detecting device with a number of detecting elements positioned in a field at predetermined coordinates in order to avoid this disadvantage and increase the reading speed and at the same time improve the local resolution on the sample. Said detecting elements, which are positioned in an imaging plane of said collecting lens, convert local resolution-detected light into electrical signals.
