2.2.1.3 FL7218/FL7040/FL7060 Sensor
Sensors in these probes include a resistance dipole, and feed a diode detector. This configuration offers a
nominally flat response with frequency. Sensors and detectors for each axis are housed in a protective
radome.
2.2.2 Detectors
2.2.2.1 FL7006 Detector
Each sensor is connected to medium barrier Schottky diode detectors. There are two diodes per probe axis to
provide a balanced output.
2.2.2.2 FL7030 Detector
Each sensor is connected to medium barrier Schottky diode detectors.
2.2.2.3 FL7218/FL7040/FL7060 Detector
Each sensor is connected to a medium barrier Schottky diode detector.
2.2.3 Preamplifiers
2.2.3.1 FL7006 Preamplifier
The detected outputs of each sensor are fed to a balanced amplitude-compressive preamplifier. They offer
dynamic bandwidth adjustment, so that larger amplitude signals exhibit a faster rise time yet small signal
sensitivity is improved.
2.2.3.2 FL7030 Preamplifier
The detected output of each sensor is fed to an amplitude compressive preamplifier. The response time is
limited by a low pass filter, offering an extended post–detection response-smoothing time constant to stabilize
the reading over the specified operating frequency range.
2.2.3.3 FL7218/FL7040/FL7060 Preamplifier
The detected outputs of each sensor are fed to a balanced amplitude-compressive preamplifier. They offer
dynamic bandwidth adjustment, so that larger amplitude signals exhibit a faster rise time yet small signal
sensitivity is improved.
2.2.4 Optical Receiver/Power Supply
The probe is powered optically. The laser light is fiber-optically transmitted to the probe. The laser light is
received via an efficient photon (light) power to electrical power converter. The electrical DC power is then
regulated, split, re-regulated and distributed to power the probe. Commands to the probe arrive in serial
optical format from relatively short interruption of the laser light. During receipt of commands, power for
operation is maintained by using excess energy that was stored in capacitors during the laser-on time.
