This paper describes an analog signal processing technique, for the development of a novel electronic circuit to be embedded in a photodiode sensor, as an integrated circuit board for electronic signal processing, to detect the energy centre of an optical signal, which represents the most accurate position measurement from a light emitter source mounted on a structure (like buildings, bridges, and mines). The Optical Scanning Sensor for (SHM) Structural Health Monitoring is proposed due to the fact that the signal processing stage is embedded in the sensor and does not require additional software processing, reducing the time and memory spacing requirements for information recording. The theoretical principle of operation, technological and experimental aspects of design, development and validation are presented.
