Using the infrared camera in the measuring technique.
Jakl, Oldřich ; Horák, Karel (referee) ; Bejček, Ludvík (advisor)
This diploma thesis is focused on using infrared camera within methods of active thermography. The first part of work is an introduction to the passive and active thermography; and about four basic methods of active thermography: step heating themography, Lock-in thermography and pulse phase thermography. The second part is a proposal of experimental working place. There are also presented results of practical implementation pulse and pulse phase methods tested for application of detection of subsurface defect.

Measurement of basic parameters of gas filters
Medek, Pavel ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
This master’s thesis deals with establishment of parameters of the PPI filter material using methods of image analysis. The first part is aimed at general methods used in practice, an overview of splitting into filter clasification and characterization of the PPI filter material. The second part represents an introduction to problems of machine vision. There are outlined basic methods of image processing. Last parts of the thesis study the method using detection of bright light levels. The measurement and interpretation of results is performed with the PPI material - types 10/6 and 10/12. For image processing is used the MATLAB program, version 7.0.1.

Diagnosis of metallic materials
Buday, Matej ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
This thesis deals with non-destructive testing (NDT). It Describes two basic thermographic methods, lock-in and pulse thermography. Different types of measurements using Fluke Ti55, points to the possibility of applying these methods in practice. Pulse thermography issue is a substantial part of this work, due to its good applicability. Also, it compares visual testing methods (VIS) and pulse thermography due to measurement with die-casting alloy AC-AlSi9Cu3 (Fe).

Vision sensor
Rášo, Peter ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
This bachelor thesis describes the vision sensors and their industrial applications. It is divided in to the 4 main parts: hardware problematic, software problematic, applications, comparison and the market survey of the vision sensors. The special part of this work is a description of working station for demonstration basic characteristics and application possibilities of vision sensor VeriSens 1200 which will be used in laboratory education. Solution of non-typical applications is described in lighting techniques. Program documentation of vision sensor VeriSens 1200 from Baumer helps with design and particular steps of this application.

Electromagnetic flowmeter
Dohnal, Zdeněk ; Bejček, Ludvík (referee) ; Beneš, Petr (advisor)
This thesis deals with inductive flowmeters, specifically insertion inductive flowmeters. It examines in detail a blueprint of such flowmeter, consisting of probe, electromagnet, electrodes, exciting module and evaluation of signal. Gauging of a flowmeter designed this way, measuring data, charts, evaluation and interpretation. Consequent measurement in a calibration laboratory to elaborate, evaluate and interpret the results.

Workplace of flow and pressure measurement
Brabenec, Jiří ; Beneš, Petr (referee) ; Bejček, Ludvík (advisor)
The thesis deals with formation of a workplace for preparation gaseous mixtures and their future usage. The main goal of the thesis is testing of new materials which have suitable usage as catalysts. Gaseous mixture is prepared by calorimetric mass flow meters with control valve and multiposition microelectric valve actuators. The next part describes measuring of pressure and temperature and controlling of furnace temperature. The thesis deals with specifications of all devices, their circuitry, communication and program controlling. All devices are controlled by computer with program which is programmed in LabVIEW.

Weather measurement
Chovanec, Jan ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
The achievement of this thesis is to design functional equipment which is able to measure the basic meteorological variables as air temperature, humidity and barometric pressure. In order to measure relative humidity completed with temperature, an intelligent sensor manufactured by Intersema Inc., MS5534B, was chosen. Relative humidity is measured by a capacitance sensor Humirel HS1101LF. The measured data are stored in anon-volatile memory. Data can be downloaded to a computer file via serial port or they can be online displayed on the computer screen via the wireless Bluetooth connection. Because the equipment is supposed to be used for the external measurement without the connection to electricity, low power consumption was considered as a most important parameter as well as good weather protection.
