Abstract:
The present invention concerns a method and an arrangement for imaging and measuring microscopic three-dimensional structures. In them, a data set is depicted in three-dimensional form on a display (27) associated with the microscope. At least one arbitrary section position and an arbitrary rotation angle are defined by the user. Rotation of the three-dimensional depiction on the display (27) is performed until a structure contained in the three-dimensional form reproduces on the display (27) a depiction that appears suitable to the user. The corresponding analytical operations are then performed on the structure.
Abstract:
The present invention concerns a method, an arrangement, and a software program for controlling analytical and adjustment operations of a microscope. The arrangement has an electronic acquisition system (50) which converts the electrical signals coming from the detectors (19) into digital signals and preprocesses them. A PC (34) receives the digital signals from the electronic acquisition system (50) and identifies from the digital signals a graphical depiction. On a display (27), the graphical depiction is displayed and moreover the user is offered the opportunity to select adjustment functions. An input unit (33), with which selection of the adjustment functions and selection of at least one structure of interest can be achieved, is provided for selection. An electronic control system (67), with which the adjusting elements of the microscope can be controlled, is connected to the PC (34).
Abstract:
The method implements time-optimized acquisition of special spectra using a scanning microscope, for which purpose the spectrum is subjected to bisecting interval measurements. The method for time-optimized acquisition of special spectra (emission spectra) using a scanning microscope is implemented in several steps. Firstly a complete spectrum to be examined, within which at least one special spectrum (emission spectrum) is located, is split into at least two intervals. The interval in which the intensity lies above a specific threshold is selected. That interval is split into at least two further intervals, and the procedure is continued until the size of the interval corresponds to the lower limit of the scanning microscope's measurement accuracy. The location of the special spectrum in the complete spectrum is defined, and an interval around it is created and is measured linearly.
Abstract:
A method for separating fluorescence spectra of dyes present in a specimen (15) is disclosed. Firstly a spectral scan of the fluorescence spectrum of all the dyes present in the specimen (15) is performed. The fluorescence spectra associated with the respective dyes are stored in a database of the computer system. After spectral deconvolution of the acquired mixed fluorescence spectrum, a comparison is made between the measured individual spectra ascertained by spectral deconvolution and the fluorescence spectra associated with the respective dyes. Lastly, a linear deconvolution of the acquired mixed fluorescence spectrum is performed.
Abstract:
As a user works at a microscope, image details are constantly present in the user's field of view. The user usually analyzes those image details, marks them with a suitable graphical software mechanism on the screen, and selects a desired function. According to the present invention, the user is offered a user interface that is based substantially on the user's knowledge of the world. A suitable combination of automated adjustment operations, automatic and semiautomatic image analysis, appropriate visualization technology, and integration is automatically used for image depiction.
Abstract:
A detector for detecting weak fluorescent radiation with a microscope system (100) is disclosed. The microscope system (100) is configured in such a way that it senses individual photons of the detected light beam (17) each as one event (50), and furnishes therefrom an output signal in the form of a characteristic function (52). A filter circuit (61) forms, from the characteristic function (52), a new characteristic function (55) that is conveyed to a discriminator (60).
