Frequency of an output signal from a Light-to-Frequency Converter (LFC) is proportional to light intensity. Under dynamic conditions, instantaneous frequency values represent instantaneous values of light intensity. In order to precisely determine frequency of the pulse signal in short time it is required to measure its successive periods. But if the light intensity changes, time between successive pulses of the output signal from LFC changes too, which prevents from obtaining the results of light measurement at regular time intervals. This work presents an algorithm for digital processing of a pulse frequency signal from LFC to obtain instantaneous values of light intensity at regular time intervals. Appropriate analytical dependences and examples of measurement results are also presented. Measurement circuit was built using DAQ-Card PCI-6602 and LabVIEW package of National Instruments. |
