Talk:Homodyne detection

Suggestion for source - Fundamentals of Photonics (Saleh & Teich)?

195.83.126.10 (talk) 14:57, 28 October 2009 (UTC)Sorry, but this article contradicts fully to Interferometry. Regarding literature I am likely to follow the latter article.   Homodyne means: NO light is shifted in frequency. (At least with respect to laser interferometry.)

It seems that the edit by IP address 86.73.72.40 : Non-classicality of homodyne measurements and the reference : T. Amri, Quantum behavior of measurement apparatus, arXiv:1001.3032 (2010). is not relevant to the encyclopedic nature of wikipedia. It may even be self promotion. The IP address 86.73.72.40 has gone about adding this reference and information rtelated to this reference at several Physics pages.

Non-linear mixing?
There's absolutely nothing non-linear about (standard) homodyne detection. - Andi — Preceding unsigned comment added by 81.194.35.225 (talk) 09:39, 24 October 2013 (UTC)

The multiplication of the received signal by local reference oscillator is a non-linear operation on the signal. You're multiplying two time-varying signals. Intellec7 (talk) 20:53, 31 October 2014 (UTC)

Wigner function
In the section about optics, it is worth noting that with homodyne detection, the projection of the Wigner function is measured on a certain axis, which rotates depending on the phase facing one of the arms. The connection of the Wigner function and the measured function is carried out by the Radon transformation. BoulatN (talk) 10:25, 12 July 2023 (UTC)
