Extending low-coherence interferometry dynamic range using heterodyne detection
(Elsevier, 2020-08)
Low-coherence interferometry (LCI) technique is generating considerable interest in industrial applications where there is a need for larger measurements with high resolution. Conventional Fourier domain systems reach a ...
On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers
is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation
equivalent to an ...
Generation of quaternary-amplitude microwave signals by using a new optical heterodyne technique
(Wiley-blackwellHobokenEUA, 2012)
Can echolocation calls of Cuban mormopid bats visualized through a heterodyne system?
(University of Puerto Rico, 2016)
Impact of the mobile terminal scheme on millimeter-wave radio over fiber systems based on photonic heterodyning techniques
(2017-06-01)
The use of communication networks relying on millimeter-wave (mm-wave) wireless links promises a great capacity enhancement as well as improved security. However, given the high-directivity of mm-wave links, coverage ...
Fiber-based Infrared Heterodyne Technology for the PFI: On the possibility of breaking the noise temperature quantum limit with cross-correlation
(2018)
We present concept and first experimental lab results for a novel heterodyne correlation receiver architecture and demonstrate that it can surpass the standard quantum limit (SQL) for the noise temperature by "correlating ...
