The development of underwater robotics sensitivity, which is based on the sensors of laser spectroscopy methods, have been discussed. The ways to improve Laser Induced Fluorescence (LIF) and Laser Induced Breakdown Spectroscopy (LIBS) methods were investigated in order to develop and create laser sensitivity for underwater robotics. A brief overview is done in the article, where LIF and LIBS spectroscopy in underwater robotics are used as spectroscopy sensors in order to investigate underwater environments by means of underwater vehicles. Limit of Detection (LoD) of oil and oil product solutions in the seawater have been detected by means of nanosecond and femtosecond spectroscopy LIF. All results, which had been received by laser pulses of different duration, were compared. The same experiments have been provided in order to measure concentrations of elements in the seawater and solutions by the LIBS method. It was discovered that the LoD of a group of elements was reduced when the femtosecond LIBS was used. Anthropomorphic complexes were under discussion in order to adopt laser spectroscopy sensors for underwater environments. The submersible module, which was constructed to investigate and examine laser spectroscopy sensors, has been described.
讨论了基于激光光谱方法传感器的水下机器人灵敏度的发展。为了开发和创造水下机器人的激光灵敏度，研究了改进激光诱导荧光（LIF）和激光诱导击穿光谱（LIBS）方法的途径。本文简要概述了将 LIF 和 LIBS 光谱学用于水下机器人中，作为水下机器人的光谱传感器，以便通过水下车辆来研究水下环境。通过纳秒和飞秒光谱 LIF 检测了海水中油和油产品溶液的检出限（LoD）。比较了通过不同持续时间的激光脉冲获得的所有结果。还进行了相同的实验，以通过 LIBS 方法测量海水中和溶液中元素的浓度。发现当使用飞秒 LIBS 时，一组元素的 LoD 降低了。讨论了拟人的综合体，以便将激光光谱传感器用于水下环境。描述了为研究和检查激光光谱传感器而构建的潜水模块。
