Electromagnetic imaging well logging can get the real-time distribution sections of the oil, gas and water in well, and identify flow regime by image, which is followed by calculating flow parameters.

Compared with traditional off-line and other on-line detection technologies, optical imaging technology is a great breakthrough in the SF6 gas leakage detection.

In order to study the growth mechanism of protein crystals, the surface morphology of(101) face of lysozyme crystals obtained by gas diffusion method was observed by AFM imaging.
