METHOD AND DEVICE FOR CALIBRATING AN OPTICAL RESONATOR, USE OF THE DEVICE, USE OF AN OPTICAL MODULATOR, AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method and to a device for calibrating an optical resonator. The method comprises the following steps: generating light pulses of a known pulse frequency by means of a light-pulse generation unit; coupling the light pulses into the resonator (20); detecting light exiting the resonator (20) by means of a detection apparatus in order to generate a detection signal, wherein the detection apparatus is designed to generate the detection signal by means of a modulator as a signal modulated with a modulation frequency, wherein the modulation frequency is substantially equal to the pulse frequency of the generated light pulses or wherein the modulation frequency is substantially an integer multiple of the pulse frequency of the generated light pulses or wherein the pulse frequency of the generated light pulses is substantially an integer multiple of the modulation frequency; and calibrating the optical resonator (20) on the basis of the detection signal. The invention further relates to a use of the device according to the invention, to a use of a switchable detector or of an optical modulator, and to a computer program product.
