In addition to basic image operations, such as zooming, rotating, warping, and smoothing, ImageJ can also perform image area and pixel statistics, spacing, and angle calculations, create histograms and profile maps, and perform Fourier transforms.
ImageJ: ImageJ can open any number of images for processing. Digital Micrograph (DM): DM has multiple functions such as image acquisition, image processing and analysis, data management and report printing. Currently commonly used software includes DM, CrystalMaker, NanoMeasure, etc. Through the analysis of TEM data, we can get the information of the sample size, particle size statistics, crystal grain size, crystal structure, crystal phase composition, atomic arrangement order and so on. TEM data analysis refers to a data processing method to obtain sample structure information through a series of measurements, analysis, and calibration of the original spectrum. It is not as intuitive and understandable as the surface topography. Due to the complexity of the sample structure and interaction, the obtained image is also very complicated. In this way, the internal structure of the sample can be understood based on the information obtained from the transmission electron image. Different structures have different interactions. The transmission electron microscope (TEM) will interact with the atoms inside the sample after the incident electrons pass through the sample, thereby changing its energy and direction of movement.
