Abstract: A multi-node data synchronous acquisition system and a method for real-time monitoring of underwater surface deformation. The system includes at least four sensor arrays, where each of the sensor array consists of a plurality of ribbon-like rigid substrates connected by movable joints. On each section of rigid substrate, three sensor units are respectively connected to a slave station data acquisition unit through cables. The slave station data acquisition unit is connected with a central controller through a cable. The central controller includes a compressive cabin outside and an embedded controller and a power supply inside. Each slave station data acquisition unit acquires data from an MEMS attitude sensor and then transmits it to the embedded controller. The present invention may realize synchronous acquisition of underwater or even underwater multi-node data, implement three-dimensional surface reconstruction, and may be used for improving the ocean observation capability.

Abstract: A measuring device for measuring a hole in the ground having at least one measuring probe having at least one measurement signal transmitter to transmit a measurement signal, at least one measurement signal receiver to receive the measurement signal reflected on a wall area of the hole, and an evaluation unit for determining a wall distance between the measurement signal transmitter and the wall area of the hole, wherein a measuring distance based on an assignment rule can be assigned to the received, reflected measurement signal. A calibrating device having at least one calibration element. The measurement signal transmitter transmits a calibration signal, which can be reflected on the calibration element, wherein the measurement signal receiver receives the calibration signal reflected on the calibration element. The evaluation unit changes and calibrates the assignment rule based on the calibration signal reflected and received by the calibration element.

Abstract: Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.

Abstract: A soil monitoring system is provided that includes a sensing shank, and a first sensor coupled to a leading edge of the sensing shank. The first sensor is configured to output first signals indicative of a pressure exerted on the first sensor by soil as the sensing shank is driven through the soil along a direction of travel. The soil monitoring system also includes a frame forming a channel oriented in a substantially vertical direction relative to a surface of the soil, and a carrier coupled to the sensing shank and disposed within the channel. The soil monitoring system further includes an actuator extending between the frame and the carrier. The actuator is configured to linearly drive the carrier in a reciprocating motion to vary a penetration depth of the sensing shank within the soil.

Abstract: Distortion models consisting of two forward and backward reciprocating planes that let a corrected image correspond to an uncorrected image for each scanning direction are constituted to let an uncorrected satellite image scanned by a reciprocating scanning sensor with scanning overlap or scanning underlap correspond to a corrected image after distortion correction, by means of a continuous mapping function on a 1:1 basis. It is determined whether each point on the corrected image is a point on an overlapping scan or on an underlapping scan or on a normal scan from the existence of a real point on the distortion models.
