Background:

Terahertz (THz) waves enable nondestructive detection of hidden objects in optically opaque materials.
Current THz inspection systems are limited by slow imaging speeds, low resolution, and data processing bottlenecks.
Machine-vision systems struggle with large data volumes from high-pixel-count imaging.

Purpose of the Study:

To develop a rapid, high-throughput terahertz inspection system for detecting hidden defects in 3D samples.
To overcome the limitations of conventional terahertz imaging and machine-vision approaches.
To introduce a diffractive sensing technique for all-optical 3D structural probing.

Main Methods:

Designed and implemented a diffractive sensor utilizing deep-learning-optimized diffractive layers.
Employed a single-pixel terahertz detector, eliminating the need for sample scanning or image formation.
Utilized terahertz time-domain spectroscopy (THz-TDS) with 3D-printed diffractive layers for experimental validation.

Main Results:

Successfully detected unknown hidden defects within silicon samples using the developed diffractive sensor.
The sensor directly outputs spectral information, indicating the presence or absence of hidden structures.
Demonstrated a significant improvement in detection speed and efficiency compared to traditional imaging methods.

Conclusions:

The diffractive sensor provides a rapid and efficient method for nondestructive detection of hidden defects in 3D materials.
This technique eliminates complex image processing, offering a streamlined approach to quality control.
Potential applications include security screening, biomedical sensing, and industrial quality assurance.
