“…In order to differentiate common underwater targets, a variety of test objects with different materials were selected, including ceramic tiles, iron sheets, and plastic, each with different material properties and varying surface smoothness, as shown in Fig 8(C). Since ceramic tiles, iron sheets, and plastic are all objects with low transmittance and high reflectance, according to references [22,23], the detectors for these three types of samples were placed in the direction of laser reflection behind the targets for measurement, as shown in Fig 8.…”

The underwater laser polarization detection technology integrates the polarization characteristics of light into the detection and identification of underwater targets. Addressing the challenge of poor accuracy in identifying targets in strong underwater scattering environments, this article proposes an overall scheme for a laser polarization underwater detection device that suppresses scatter using polarized pulse signals. By overcoming key technological barriers in the design of polarization-preserving optical detection systems and utilizing the method of differential amplitude to measure polarization, a laser polarization underwater detection device was developed and underwater polarization detection experiments were conducted, achieving precise detection of underwater targets. The results indicate that the underwater detection device we designed has a root mean square error of less than 5.7% to detect the polarization of the target, demonstrating the accuracy and precision of the underwater detection device.
