A computer controlled signal averaging spectrometer system Thewalt, Michael Ludwig Wolfgang


A high sensitivity infrared spectrometer with signal averaging capabilities was constructed for the detection and analysis of luminescent light. The apparatus was interfaced to a Nova- 2 minicomputer which was used to control all aspects of the experiment in progress. Two programs were written for this system: one in machine language through which programs written in a higher level language can communicate with the interface, and one in the Basic language which contols the spectrometer when collecting data. Other programs which have been written for data analysis will not be described here. An example of work currently being performed with the new system has been included. The detection of several heretofore unknown lines in the luminescence spectrum of Si gives evidence of the high sensitivity of this apparatus.
