Four-Channel Optical Power Meter With Display Probe External
The four-channel probe external optical power meter is usually
composed of a photodetector, an amplifier, a filter, an
analog-to-digital converter and a microprocessor. In the
measurement process, the optical signal is received by the
photodetector and converted into an electrical signal, which is
processed by the amplifier and filter, and then converted into a
digital signal by the analog-to-digital converter, and finally
processed and displayed by the microprocessor.
The working principle of the four-channel probe external optical
power meter is based on the photoelectric effect, that is, the
optical signal is received by the photodetector and converted into
an electrical signal, and then amplified, filtered and digitized
through the circuit, and finally the power value of the optical
signal is obtained. Since it has four channels, the optical signal
power of four different optical paths can be measured
simultaneously.
