Optimetric Measurements Over Coherent Free-Space Optical Communication

High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...

Briefs: RF & Microwave Electronics
Gated Chopper Integrator (GCI)

Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...
