3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Confocal microscopy confocalmicroscopy; CM Using constrained illumination and confinement detection, an optical tomographic image is obtained by axial scanning and by extracting the maximum axial signal position Determination of the surface area of a given sample. Note. The mask pattern that achieves the illumination and detection constraints may be any mask pattern capable of generating tomographic features, such as single point, multi-point, grid, or slit. 3.2 Lighting pattern iluminationpattern Use a specific graphic structure to define the illumination of the sample being illuminated. 3.3 Detection pattern detectionpattern The use of a specific graphic structure limits the way in which the detector receives the area of the imaging signal area of the sample. 3.4 Optical chromatography capability opticalsectioningstrength The degree to which the confocal microscope prevents the defocussed optical signal from being received by the detector. 3.5 Plane scanning in-planescanning The mechanical or optical displacement of the confocal tomography image is obtained in the xy plane. 3.6 Axial scanning of axialscan A mechanical or optical shift in the optical axis direction (z-direction) results in a change in the in-focus position of the sample. ......
