【Abstract】 This paper presents qualitative and quantitative analysis and calculation of errors caused by assembly processes of optical elements in IM 85-1 fiber optic pressure liquid level sensor system. A new rational and precise optical assembly process is developed so that the sensor is immune to various adverse effects of alignment errors, and its high sensitivity and stability are ensured. The measurement accuracy of the sensor system reaches 0. 2%.更多还原
