Digital interface for quadrature demodulation of interferometer signalsa
We describe a digital interface for processing signals produced by a scanning multichannel far‐infrared interferometer/polarimeter for plasma density measurements. The interface samples the interferometer signals in quadrature before digital filtering, demodulation and downloading to a transputer ar...

| Zusammenfassung: | We describe a digital interface for processing signals produced by a scanning multichannel far‐infrared interferometer/polarimeter for plasma density measurements. The interface samples the interferometer signals in quadrature before digital filtering, demodulation and downloading to a transputer array for real‐time tomographic inversion and display. |
