An acousto-optic sensor is a device that measures specific physical properties, such as pressure, temperature, or strain, by utilising the interaction between sound waves and light waves. A photodetector and an acousto-optic modulator (AOM) are its standard components.
The AOM is a crystal or substance that can produce sound waves in response to an electrical stimulus. The phase and amplitude of the light waves travelling through the crystal are modulated by periodic fluctuations in the refractive index caused by the sound waves as they go through it. A photodetector then recognises this modulation by turning the modulated light into an electrical signal.
The sensor can determine changes in the physical parameter being measured by examining the electrical signal. For instance, in a pressure sensor, the AOM’s sound waves can be utilised to produce pressure waves in a liquid or gas, which alter the AOM’s refractive index. The photodetector notices this alteration, and the electrical signal that results is proportionate to the pressure.
Compared to conventional sensors, acousto-optic sensors provide a variety of benefits. They can assess a variety of physical characteristics with high accuracy and sensitivity while being non-invasive and operating in challenging situations. They are utilised in many different applications, such as environmental monitoring, industrial process control, and medical imaging.
Global acousto-optic sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
With a 40% global market share, Frauscher Sensortechnik GmbH is the industry and market leader in inductive sensor technology solutions. Thry are constantly expanding their product line in order to support its continued development.
The project being promoted intends to advance and commercialise distributed acoustic sensors and fibre bragg grating technologies for use in railway applications. Modern inductive sensor technology has several limits, thus the new technology should be used in addition to it.
A technical, economic, and regulatory assessment will be done as part of the proposed feasibility study in order to establish a business strategy., it will serve as the foundation for an innovation initiative (phase 2 of the SME implementation).
Frauscher Sensortechnik GmbH will have branches all over the world to enable the commercial exploitation of the development. The new technology will enable the organisation to grow continuously.
