Description
Summary:A hardware and software measurement system is developed and implemented based on a high-sensitive accelerometer and a computer with multichannel analog-to-digital converter (ADC). The system makes it possible to detect inhomogeneities of the Earth’s crust using Rayleigh surface waves. The measurement system consists of four universal piezosensors connected to the ADC, the debug stabilization board, the board battery, and the fiberglass base with slots for each sensor. The upper frequency limit of the measurement system is 20000 Hz. Software made by L-Card is used when working with the ADC. This software makes it possible to record data without size restrictions under multimodule operating mode and at any sample rate. All parts of the system are detachable, which ensures its small size and versatility when operating in the field. In this paper, a detailed description of the system is given, and the results of its testing by determining the velocity of Rayleigh surface waves in homogeneous media are presented. A detailed description of the experiments is provided, as well as the results of the use of the system for the detection of near-surface inhomogeneity in order to confirm the effectiveness of and evaluate possible prospects for the microseismic sounding method.
