What Is an Optical Probe?
Optical probe is electrolytic probes that overcome the shortcomings of conventional electrolytic probes and retain the sensor portion without metal elements. It uses electro-engineering effects for accurate measurement and evaluation.
Features include the non-invasive nature of its optical fiber that does not disturb the electric field, does not pick up noise, the sensor head is small and does not require a power supply. There is also a wealth of information that can be measured, such as frequency, phase, and intensity, and interference does not occur even if metal is present in the surrounding area.
Uses of Optical Probes
Optical probes are also used in controllers, oscilloscopes, and endoscopes to measure a variety of information for investigation and analysis purposes using optical means.
Applications include the measurement of pulsed and ultra-strong electric fields in EMC design and for the purpose of verifying simulation models.
It is also used for purposes such as evaluating antennas and probing differential voltages.
Principle of Optical Probes
Optical probes use EO crystals for the head part, which have an effect called the Pockels effect, in which the refractive index changes in proportion to the applied electric field.
When no electric field is applied, the incident light is reflected while maintaining its polarization state. When an electric field is applied, the crystal surface changes its refractive index depending on the polarization state, and the polarization state of the incident light changes and returns.
The changed polarization state is then converted into a signal of light intensity change using a detector, etc., which is then converted into an electrical signal to obtain a signal proportional to the electric field intensity.
Optical probes are not affected by noise because the signal is transmitted over an optical fiber. This allows transmission over long distances by converting a voltage signal into an optical signal without being dependent on frequency.
