Output signal from a position sensitive detector illuminated by means of an optical fiber was measured. Light sources were light emitting diode CQYP 06W or CQDP 42 W. Linear characteristics of the signal height as a function of light spot positions were obtained. Output signal from the detector was also measured using two optical fibers with a fixed distance between them. The measured slope of the linear characteristic for one optical fiber was a1 = [10,49 ± 0,14] mV/mm and for two optical fibers: a2 = [20,07 ± 0,20] mV/mm Use of two optical fibers causes a rapid change of the output signal and results in a sudden jump of the characteristic slope. The results point to a possibility of an application of position sensitive detectors for an analysis of light spot position using one or more optical fibers.
