“…Among scattering suppression techniques, CW techniques are useful in practice because of their simplicity and stability of measurement. For example, techniques to detect ballistic photons [9,10] and near-axis scattered light (NASL) [11,12] have been reported based on these practical advantages. However, ballistic photons can reach the detector across body tissues of only a few millimeters' thickness, and NASL can reach the detector after penetrating body tissues of about 10 millimeters' thickness.…”

Transmitted light through a diffuse scattering medium includes strongly diffused light (SDL) and weakly scattered light (WSL). To realize clear transillumination imaging through thick body tissue, which is typically more than 10 mm, we developed a technique to extract the WSL component from diffused light. In experiments using a 15-mm-thick scattering medium (µ s ' = 1.0/mm), the cross-section of the light propagation area at the center of the medium was confined to a 50% area. This method's usefulness was demonstrated by transillumination imaging through a 40-mm-thick piece of chicken meat. The possibility of depth evaluation was also verified. References and links 1. S.

“…Started with radio communications [2], coherent detection methods being expanded to the optical domain [3]. Nowadays there is a broad range of examples of optical coherent detection usage in lots of different fields including communication [4,5,6,7,8] and quantum optics [9,10,11]. One of the promising technology at the boundary between communications and quantum optics is quantum key distribution (QKD), which, in combination with coherent detection, leads to a separate branch known as continuous variable (CV) QKD [12,13,14,15,16,17,18].…”

In this paper, we demonstrate different approaches to coherent detection implementation in subcarrier wave quantum communication schemes. In order to extract information from quadrature phase-coded multimode signals, we demonstrate models of homodyne, double homodyne, and heterodyne detection, actively using the properties of such signals to implement. For greater clarity, all mathematical calculations are given in terms of wave optics. The feasibility of the proposed schemes is supported by experiments.
