GB/T 12604.2 Terminology for nondestructive testing radiographic testing3 Terms and DefinitionsGB/T 12604.2 defined and the following terms and definitions apply to this document. 3.1 Ray film digitization systems radiographicfilmdigitisationsystem Transmittance, the transmittance of the reflected signal output by optical detector detects the film, and the electrical signals into digital signals to Computer, a digital image is formed. Acronym Digital System. 3.2 Scanning aperture (SA) scanningaperture Digital image scanning film formed on the region corresponding to one pixel. Scanning aperture size is to determine the spatial distribution of digital systems Resolution of the main factors. 3.3 Pixel size (P) pixelsize Scanning the image formation, each row (horizontal) or a (vertical) distance between the centers of adjacent two pixels. 3.4 The optical density (D) opticaldensity Through the irradiation light intensity and film transillumination light intensity ratio of the common logarithm. According to equation (1). D = lgIoID (1) Where. Io --- irradiation light intensity; ID --- through the transparent film according to the light intensity. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 28266-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 28266-2012_English as soon as possible, and keep you informed of the progress.
