Abstract

A light/voltage converter circuit for converting intensity fluctuations of light into an alternating voltage measurement signal includes a photodiode configured to detect the light and a transformer comprising a primary coil and a secondary coil. The primary coil is connected in a series circuit to the photodiode, and the alternating voltage measurement signal is applied to the secondary coil. An electrical network is configured to block direct current and conduct alternating current. The electrical network is connected in parallel with the series circuit consisting of the primary coil of the transformer and the photodiode.
