The homebuilt laser and its application Bálint Kollek, István Csanády

First steps ‣ Advantages: -The whole project based on one person’s idea ‣ Disadvantages: -You have to be good at everything -It’s hardly possible Working in group or alone?

The “woodlaser” ‣ Why wood? - It’s cheap - It’s easy to work with wood

The complete laser

Increasing the performance ‣ Building the line of magnets - the switches and the magnets ‣ Measuring the performance and the magnetic field

Homogeneity checking How does it work? ‣ Using diffraction ‣ Comparing diffraction results to the standard signal Standard Defect

Homogeneity checking ‣ The light-sensor and the signal generator The four parts ‣ The brackets ‣ The laser ‣ The electric reel

How does it work? Laser Electric reel Sensor OK Computer Defect

Writing the inspector ‣ Testing the sensor with oscilloscope The image of the“good” and the “bad” signal ‣ Using the simplest solution: checking the scatter of the signal ‣ Digitalizing the signal with a soundcard
