Security scanner


Fast and accurate security scanning

Premix’s material innovation enables faster and more accurate security scanning technology in Xin Ying Science and Technology’s three-dimensional SIMImage™ -human scanners.

The global need for monitoring and ensuring people’s safety has created a growing demand for fast and accurate security scanning. This applies to the aviation and railway industry as well as government and other high-security facilities, not to mention protecting human lives from security threats in mass events. To meet this demand, Xin Ying Science and Technology and Premix proudly present the SIMImage™- MD-02A.

Significant improvements in capacity, resolution and scan range

The SIMImage™ is a millimeter wave active imaging system with a scan time of 2 seconds and throughput of 400 persons per hour, whereas a conventional device scans roughly 100 persons per hour. Besides the larger capacity, the scan resolution and scan range of the SIMImage™ are substantially better, making it the winning solution for security scanner needs.

The technological innovation behind the better visual image is based on Premix’s unique PREPERM® material solution.  PREPERM® replaced the old PMMA based radome material due to superior properties: It has ultra low loss and a very constant sheet quality in terms of dielectrics. Thanks to the new material, the SIMImage™ image quality is close to X-ray, but without the harmful effects for the human body. Dr. Wu Liang from Xin Ying Science and Technology gives credit to the collaboration:

Premix was the only material supplier who was able to offer the solution matching our needs. The extruded PREPERM® sheet with customized dielectric properties matched exactly to our specification.
