New Product | Phsonic Optical Detector for Non-Contact Ultrasonic Detection-Optizone Technology (Shenzhen) Limited

As smart manufacturing accelerates and quality control standards rise across advanced industries, non-destructive testing (NDT) has become a critical quality assurance mechanism in aerospace, new energy, composites, and electronics.

Ultrasonic Testing Limitation

Conventional piezoelectric ultrasonic testing faces significant limitations: it requires coupling media, is susceptible to electromagnetic interference, and lacks high-frequency capability — falling short in complex operating environments and high-precision inspection demands. The global non-destructive testing market continues to grow, with ultrasonic inspection remaining the dominant method. The industry is advancing along four directions: higher precision, non-contact measurement, intelligent automation, and domestic self-reliance. Traditional contact-based probes risk damaging precision workpieces and cannot operate effectively under high-temperature, high-electromagnetic, or long-distance conditions. Meanwhile, imported high-end optical acoustic instruments come with steep price tags and slow after-sales support, hindering domestic manufacturers from achieving cost reduction and quality improvement targets.

Against this backdrop, non-contact high-frequency optical acoustic sensing presents a compelling opportunity. The market urgently demands a domestically developed, fully self-reliant optical acoustic instrument with top-tier performance and universal applicability. As China's first high-frequency optical acoustic instrument supplier, Optizone Technology has built deep expertise in laser interferometry. Leveraging fully proprietary, domestically developed core technology, we have launched the Phsonic Acoustic Detector. Featuring an all-fiber optical sensing architecture, Optizone Technology breaks through international technology barriers with industry-leading performance across a wide range of industrial applications. It fills the gap left by the absence of domestic high-end alternatives, offering the market a truly self-reliant new option for non-destructive testing.

Principle

Phsonic Acoustic Detector is an ultrasonic sensor based on laser interferometry technology, achieving high-precision acoustic wave detection by measuring slight changes in air refractive index.

It can be applied to scenarios such as non-contact non-destructive testing and high-frequency acoustic wave detection. This type of optical microphone features high sensitivity, wide bandwidth, and a compact structure. It does not require an acoustic wave matching medium and does not rely on inertial components for sensing. The measured sound pressure signal has no tail oscillation. Moreover, it adopts an all-fiber structure, is not affected by the external electromagnetic environment, and has

The Phsonic Acoustic Detector integrates five core advantages — compact size, high sensitivity, high resolution, wide bandwidth, and wide dynamic range — into a product. Three models precisely cover distinct frequency bands and operating conditions, balancing general-purpose inspection with high-frequency precision detection.
