Abstract

A microcomputer-based spectroscope using CCD as sensor was designed, implemented and evaluated The implementation of the system included the setting up of the CCD camera mount and the spectroscope, installation of the PCVision Plus Frame Grabber hardware and the development of the software that would facilitate in capturing, processing and analyzing the image which correspond to the line spectra of the element The developed software allows the user to analyze elements and has options to save data as text files and retrieve them for future uses. It also has a feature that would generate characteristic line spectra given wavelengths which will be specified by the user The program also incorporated some image processing algorithms for the spectral image such as image filtering and image bleeding correction. The first process functions such that data can be filtered from external noises generated by stray lights and the second process functions so as to correct the seemingly widened spectral lines brought about by the high intensity of the image's brightness The program also computes for the wavelengths and photon energies of the element at each line and displays them together with the graphical representation. The system was calibrated using the hydrogen and the helium discharge tubes and was tested on the other gas discharge tubes as well.
