- A global first: non-destructive 2D and 3D analysis utilizing Terahertz wave
The TAS7000 enables non-destructive, 2D and 3D analysis of the internal composition and structure of measurement targets, utilizing computed tomography (CT) and exploiting the unique properties of terahertz waves.
The TAS7000 enables not only analysis of the structural homogeneity of an internal substance, but also identification of constituents and quantitative distribution measurement.
Moreover, in contrast with other regions of the electromagnetic spectrum, terahertz waves can penetrate various types of materials with moderate transmittance, allowing for analysis.
- High-speed measurement utilizes Advantest's terahertz optical sampling technology
The TAS7000 relies on Advantest's newly developed, ultra-short pulse femtosecond optical fiber laser technology for terahertz wave generation and detection, and utilizes the company's original terahertz wave high-speed optical sampling technique. Thus, it delivers measurement throughput approximately 1000 times greater than the previous system.
- Broadband terahertz wave spectroscopic analysis up to 3THz
The TAS7000 enables broadband, high-resolution spectroscopic analysis up to a maximum analytical frequency of 3THz. The system is ideally suited for acquiring fingerprint spectra of a comprehensive range of chemical, industrial, and biological materials. For high precision, the system has the option to remove water vapor from the sample chamber by flowing dry air during the measurement.

Non-Destructive Analysis of Ceramic Filters for Reduction of Diesel Engine Emissions
Novel method for non-destructive analysis of ceramic filters
The DPF(?1) is a key component of the after-treatment system that reduces emissions from diesel engine exhaust gas. Analyzing accumulated PM(?2) such as soot and ash in a DPF is critical for optimizing the after-treatment system.
The TAS7000 enables non-destructive analysis of the 3D-PM(?3) distribution in a DPF, as well as soot and ash analyses.

DPF Analysis with the TAS7000
When a DPF sample is placed on the CT test bench, it is scanned with broadband terahertz radiation. By analyzing the spectral characteristics of the radiation transmitted through the sample, the system can display a data-rich graphics of the internal structure and quantitative distribution (g/L) of PM within the sample.

Advantages of the TAS7000 for DPF Analysis
- Optimizing product quality using 3D quantitative distribution analysis
The TAS7000 enables PM quantitative distribution (g/L) analysis in arbitrary areas within DPF samples, allowing developers to obtain data to visualize the thickness of soot and ash layers in detail, and to assess any changes in the internal structure of the filter. This data can facilitate the design of optimal after-treatment systems.
- Improving R&D efficiency
By making it possible for the first time to analyze filter samples without physically dissecting them, development time can be sharply reduced. Additionally, repeated analyses of the same sample are possible, allowing for confirmation of results and monitoring changes in follow-up investigations.
- Ease of operation
No complicated setup is necessary. Samples are simply placed on the CT test bench.
