Definitions
- the invention relates to a method and a system for the central computer-controlled execution of at least one test procedure in a scanning microscope, in particular a confocal microscope, in which at least a first software module of an application software is tested.
- a sample of a microscopic specimen is scanned pointwise with a light beam.
- lasers are used as light sources. It is possible to use mixed gas lasers, diode lasers, solid state lasers but also so-called white light lasers.
- White light lasers have the advantage that a spectrally broad, continuous light spectrum is produced.
- a confocal microscope is provided with a workstation which, through various interfaces with the components of the scanning microscope such as the detector, the detection pinhole, acousto-optic components with a programmable beam splitter such as an AOBS, acousto-optic components selectively depending on radiated radio frequencies to individual wavelengths act as an AOTF 1 the scanner and other components is connected.
- the control of the microscope is made by means of an application software on this workstation, which is a decentralized island solution. If problems arise with the device, a service technician must be informed, who will try to solve the problems on site.
- the object of the invention is to specify a system and a method with which a remote test of at least one software module from the application software can be carried out in a simple manner.
- the operating parameters of a scanning microscope are to be determined by means of a remote test. This is to ensure the optimal functionality of a scanning microscope for the user.
- the invention solves the problem by a network consisting of individual scanning microscope clients and a central server.
- the clients can be addressed via a network interface and are managed in a central directory in the server.
- the application software for the individual components of a scanning microscope consists of individual software modules, each of which is assigned to a possible test. To perform the various tests, on the hardware side, the scanning microscope clients were equipped with additional sensors and components that make it possible to determine various operating parameters.
- Fig. 1 is a schematic representation of a scanning microscope with a
- Fig. 3 is a schematic representation of a scanning microscope with a
- Fig. 1 the schematic structure of a confocal scanning microscope 1 is shown.
- the illuminating light beam 3 coming from a laser 2 is directed to a scanning device 5 by a beam splitter 4, which is embodied here as an AOBS, or another suitable deflection means. Before the illuminating light beam 3 strikes the beam splitter 4, it passes through an illumination pinhole 6.
- the scanning device comprises at least one scanning mirror 7 which guides the illuminating light beam 3 through a scanning optics 8 and a microscope optics 9 over or through an object 10.
- the scanning mirror 7 is driven by a motor, not shown here.
- the illumination light beam 3 is guided over the object surface in the case of non-transparent objects 10. For biological objects 10 or transparent objects, the illumination light beam 3 can also be guided through the object 10.
- non-luminous preparations are prepared with a suitable dye and these dyes present in the object 10 are excited by the illuminating light beam 3 and emit luminescence and / or fluorescent light in a characteristic region of the spectrum which is their own.
- This light emanating from the object defines a detection light beam 11.
- the dekektor unit can consist of at least one photomultiplier , It is also conceivable that the detector unit 13 consists of a photomultiplier array or a CCD chip, an EMCCD chip or an APD array.
- the detector unit are electrical, for the output of the object 10 outgoing Produces light, proportional detection signals. Since light of not only one wavelength is emitted by the object 10, it makes sense to provide a dispersive element in front of the detector unit.
- the dispersive element spectrally splits the detection light beam so that the individual wavelengths of the detection light are spatially separated.
- an acousto-optical component such as an AOTF 14 is furthermore provided with which the respective desired wavelength can be selected from the wavelength spectrum.
- a work computer 15 For computer-aided control of the individual components, a work computer 15 is provided, which has various interfaces for the individual device components. On the work computer 15, an application software is installed, which consists of various software modules for the individual device components. The work computer 15 is connected to a control server 17 via an Internet connection 16. As a result, the individual scanning microscopes can be addressed via a network interface and managed in a central directory.
- JINI is a framework for programming distributed applications that place special demands on the scalability and complexity of collaboration between the various components and can not be serviced by existing techniques. JINI was developed by Sun Microsystems based on the Java programming language. JINI includes a directory service that can be used to discover device features and other services. The directory service then provides both the network address and the necessary interface descriptions; the devices and other services are called via "remote method invocation".
- the laser scanning microscope was therefore extended according to the invention by components that enabled automatic detection and detection of different operating parameters.
- FIG. 2 This is illustrated in FIG. 2 for a beam splitter (AOBS) test: mirrors and polarizing filters 21 introduced into the intermediate image and an integrated reference diode 23 allow the beam path to be checked by the AOBS 4. From various setting parameters and the resulting intensity values at the detector 13 can be determined the correct calibration.
- AOBS beam splitter
- a detector test is shown, which is made possible by means of an integrated light source 25.
- An LED 25 or other light source near the photosensitive surface of the detector can simulate a signal.
- the entire signal path from the LED 25 to the detector 13 can be checked.
- further tests are possible.
- the galvanometers in the scanning unit 5 can be checked: With a test structure which can be introduced motorized at the position of the intermediate image in the beam path, it is possible to check the size of the scan field and thus the function of the galvanometer of the scanner 5.
- a check of the laser or the AOTF is possible by means of a reference diode behind the AOTF. This allows you to check the AOTF calibration and the laser function.
- conclusions can be drawn on the service life of laser and AOTF from the passage of time of the measured laser powers and specification values.
- the spectrometer can be tested by comparing the wavelengths emitted by the laser with the wavelengths actually measured by the instrument.
- a pinhole test is possible via a mirror at the position of the intermediate image. With an internal detector, the intensity of the light is determined as a function of the pinhole diameter. From the course the correct adjustment of the pinhole can be read.
- the stepper motors in the microscope can be tested by the control electronics:
- the control electronics of the stepper motors allows a query open or shorted connections. In a targeted back and forth with subsequent search of the original position can be detected step losses.
- the beam path in the microscope can be changed or switched via different apertures.
- the position of the diaphragms can be determined or interrogated optically, magnetically or via other detectors or sensors. Furthermore, it is conceivable that for reasons of laser safety in the case of a defective aperture an alarm signal is output.
- the tests mentioned here by way of example are carried out remotely in a confocal laser scanning microscope from a central server.
- a software module can be assigned to a respective test in the application software.
- These software modules of the application software are listed in a configuration file, which in turn is stored centrally in the server and can be called from there. It can then be independently called different software modules of a respective scanning microscope client.
- the central server and the various Scanmikrsokop clients in a network different variants are possible:
- the execution and transmission of the test results for a scanning microscope client advantageously proceeds according to a test plan. For example, for each test on a scanning microscope client, a time interval after which a retry is performed may be defined. If possible, only so many tests are carried out that there is no impairment of normal use.
- test results are then automatically transferred to a central control server 17 and stored in a "remote diagnostic database.”
- the test results can also be stored directly on the scanning microscope client, comparing the results for the different scanning microscope clients.
- the evaluation of the collected data then takes place, for example, under the aspect of maximum failure-free time and / or maximum performance of the devices in the field. This includes, for example, the automatic initiation of suitable measures, eg recommendations for ordering spare parts based on self-diagnostics.
- suitable measures eg recommendations for ordering spare parts based on self-diagnostics.
- the expected lifetimes of the lasers can be estimated in advance or optimized service schedules of the most critical devices can be created.
- the "Remote Diagnosis Database” can also be linked to other databases so that, for example, also the acceptance of the serial number of the device, acceptance protocols, SAP data, support requests, board revisions and the like can be called up.
- statistics are generated based on the operating parameters in the field. This can detect any deviations from the standard or weak points of the device and then a targeted service can be performed. It is also conceivable to carry out an analysis of the user behavior whose evaluation leads to the optimization of typical processes for certain types of experiments.
- the overall average failure-free time can be substantially extended. This includes the transmission of simple tests and measurements (for example from log files) as well as self-tests / "performance tests" carried out according to a test plan at specific times.
- the most important aspect here is that a first diagnosis is made "remotely", ie without the need for a local service technician, in the ideal case deviations of the parameters and thus an imminent failure are detected, before a disturbance that is recognizable to the user actually occurs ,
- the entire history of the boards installed in the device can be traced on the basis of individual and readable serial number chips on each board.
- the temperatures and coolant flow rate / levels at different points in the device as well as the supply voltages of the individual components are transmitted at regular intervals. Also, the available memory, control parameters of the galvanometer and other calibration values can be directly recorded and transmitted.
- An integral part of remote diagnostics in laser scanning microscopes are the self-tests that are performed automatically. These are performed, for example, at the start of a scanning microscope client (preferably tests of short duration for some device components) or when switching off the device. However, the device can also detect if there has been no measurement or user action over a long period of time, and then use these phases (idle phase) for complex self-tests.
