TL;DR: A high-speed air-water optical wireless communication system with both downlink and uplink transmission employing 32-quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) and a single-mode pigtailed green-light laser diode (LD).

TL;DR: It is proposed that self-powered solar panels featuring large receiving area and lens-free operation have great application prospect in underwater vehicles or underwater wireless sensor networks (UWSNs) for data collection and the impact of water turbidity on the solar panel-based underwater wireless optical communication ( UWOC) is investigated.

TL;DR: An underwater wireless optical communication system using an arrayed transmitter/receiver and optical superimposition-based pulse amplitude modulation with 4 levels (PAM-4) and a spatial summing scheme using a light emitting diode array, which is divided into two groups in a uniformly interleaved manner is proposed.

TL;DR: It is uncovered that the level of security the authors have traditionally taken for granted on underwater wireless optical communication (UWOC) may not always be there and the possibility of information leakage increases, which may pose a great threat to the security of UWOC.

TL;DR: In this article, an underwater historical relic integrated detector based on an ROV platform is presented, which comprises a deck device and an underwater integrated detector, and belongs to the ocean exploration technology field.
