This Master’s thesis solves a design and construction of device for gathering and transfer of data into computer. The device should replace graph plotter, by which is measured the optical intensity of a laser beam. From this characteristic it is possible to determine other parameters of the laser beam, such as halfwidth of the beam, angle of divergence and Rayleigh length. The described device - “data gatherer” - measures two voltage values – voltage detected on photodiode and voltage detected on distance moved by photodiode. Measured values of voltage are processed and sent through a serial line into the computer. A pre-amplifier is connected to the control part for both channels of measured values with possibility of amplification. Computer application, which performs graphic interpretation of the measured values, serves as user control peripheral. The product of this project is compact device operating under OS Windows with graphic output.
