ofdynamic vibration; such as in a turbine rotor or a fan blade, they would have touse either two lasers or measure the same points from two different angles. Thesesteps result in an increase in cost and time. Page 11.960.4Page 11.960.5Proposed System:The main application of this laser measuring system is to measure displacement in2-axis in order to determine dynamic vibration. This system consist of a laserbeam reflected into a position sensing detector (PSD) off a reflective tape (1x1mm) which is placed on the surface of the object to be measured.The PSD consist of a resistive layer which creates an electric charge proportionalto the laser bean intensity that is

Page 11.1196.7The IMAQ Read LCD VI is which also comes with LabVIEW’s VISION software then uses theROI for each seven segment display to determine each segments status and digit. This ispreformed by doing three edge detections, two horizontal and one vertical. The horizontal edgedetections are preformed at 1/3 and 2/3 the height of the ROI to determine if the verticalelements are active. The vertical edge detection search is preformed to determine if thehorizontal elements are active.6 Figures 9 shows the LabVIEW DMM Reader VI front panel.Notice that the proper reading is extracted despite considerable reflected glare on the displaycover. Figure 10 show the front panel and block diagram respectively for the DMM Reader VI

dual-receiver systems thatuse differential approach to positioning. Sub-centimeter accuracies, accomplished bydifferential GPS may be adequate for construction purposes; nevertheless, it may be costprohibitive for the near future. A second option is the use of laser guided robots that willmove by following line of sight laser. The principle of such beam guidance will be basedon image recognition of the laser reflection recognized by the image analysis of thecamera. Alternatively, a photodiode array can be directly used to replace the camera forwhich the principal of robotic guidance operation will remain the same. A laser scannerwill be needed to scan the laser beam along the desired contours. Laser shows exhibit thecapabilities of laser

theoretical aspects of the topics while on focusingmore attention to the implications in design, analysis and applications. It is desirable thatthe students can experiment in a university lab with the measurement and control ofindustrial systems and investigate the technological aspects of these systems. The resultsof the experiments in the laboratory are expected to reflect the trends in that specificindustry sector. To make a positive, continual, and lasting contribution to I&M education,upon completion of the project, WSU and FH will:• Establish a cost-effective and cooperative/distributed I&M laboratory on both the WSUand FH campuses to provide hands-on experiential education to a diverse-studentpopulation.• The I&M (WSU-DET+FH

Further, thesame circuit is used with the Computer Aided Spectrum Analyzer.For the second instrument in Part 2, the principles of operation of a Time DomainReflectometer (TDR) are discussed. A block diagram shown in figure 4 was first illustrated,then the theory of determining the nature of fault and its location were discussed usingfollowing equation: Fig. 4- A Simple Block Diagram Showing the Principle of TDR z1 − z c Γ= (4) z1 + z cΓ is the reflection coefficient and z is the impedance of load and the characteristic impedance ofthe

bend the beam with the appropriate displacement.Based on the mathematical model developed to simulate the real beam experiment, the outputstrain and voltage values appear on the screen of the strain gage indicator.ConclusionThis paper presents the development of a virtual laboratory which enhances the students'understanding of physical concepts by providing a high degree of immersion within richinteractive learning environments. The experimentation system integrates dynamic andinteractive simulations in stand-alone and Web-based environments. During the experimentationphase, changes in parameters and variables are immediately reflected in the graphical userinterface. Thus, the students can visualize in real time how the model behavior

of vibration analysis. The instruments arealso familiar to the campus students from experiments carried out in the traditionallaboratory comprised in e.g. the undergraduate signal processing courses.The experiments in the remote laboratory is designed to reflect on authentic vibrationproblems in the manufacturing industry, e.g. vibration in metal cutting processes.5, 6, 7The object under investigation is a boring bar used for metal cutting in a lathe. Vibrationproblem associated with this type of process is considered to be an important and criticalfactor concerning the performance of, the tool life, the surface finishing, etc. whichfinally ends up on the production cost negatively. Since it is shown that vibrationproblem originates from the
