Introduction to High Resolution Terahertz Imaging System
>>Imaging effect demonstrationvideo
The high-resolution terahertz imaging system launched by Shanghai Yichi Optoelectronics mainly consists of a uniform terahertz illumination source, a terahertz camera (including an anti reflective film), and a focal plane imaging terahertz lens (including an anti reflective film). The imaging effect of the high-resolution terahertz imaging system is shown in the following figure:

Terahertz cameraMICROXCAM-384I-THZ is based on the principle of uncooled and microbolometer, specifically developed and optimized for signal detection in the THz band. Detectable wavelength range: 70um-3189um. The pixel size is 35um, and the equivalent noise power is on the order of PW. Due to its long sensing wavelength, it can provide penetrating imaging for many objects (such as ceramics, textiles, plastics, fur or cardboard boxes, and other non-polar substances). The camera has high sensitivity over a wide wavelength range.

Uniform terahertz illumination sourceWe mainly provide two frequency points, 282GHz and 515GHz.
Terahertz imaging systems are mainly used for penetration testing imaging to explore the internal structure of the package. The default imaging method is transmission imaging. In this case, the terahertz camera and terahertz source are placed on both sides of the imaged object, respectively. Of course, imaging systems can also be used as a reflective imaging solution.
