The phrase "absolute thickness" is correct and usable in written English.
It can be used in contexts where you are discussing the precise measurement of thickness without any variation or relativity.
Example: "The absolute thickness of the material is crucial for ensuring its structural integrity in construction."
Alternatives: "exact thickness" or "definite thickness".
The overall cortical and trabecular bone density (D100), the absolute thickness of the cortical bone (CTh), and the absolute number of trabecules per area (TbN) were significantly lower in AN patients compared with healthy young women.
In addition, a novel technique to determine the volume fraction of the fine γ′ precipitates without the need to determine the absolute thickness of the TEM foil is proposed.
The type of behavior depends (i) on the ratio between the bulk stiffness of the layers (EA/EB); (ii) the ratio between the thickness of the layers (tA/tB); but also (iii) on the absolute thickness of each layer (tA, tB).
The scattering of the G band intensity is too large to use it as an absolute thickness measurement.
The relative thickness variation, measured by HAADF-STEM and the absolute thickness variation, measured by the phase images are given in (c, d).
Therefore, the G band intensity cannot be used as an absolute thickness measurement but rather as a first guess if the relative extinction cannot be measured.
Though the structures and sizes of these 2-D patterns are typically scale-free, they are also characteristically anisotropic; that is, the number of layers and their absolute thicknesses vary significantly during formation.
The absolute specimen thickness, measured by the phase variation, reveals a specimen thickness in CIGS of 50 60 nm which agrees well with values measured by EFTEM, i.e., 50 80 nm.
In this research, the absolute optical thickness and surface shape of a 6 mm-thick fused silica transparent plate of diameter 100 mm was measured simultaneously by a three-surface Fizeau interferometer.
The primary visual cortex ROI shows a remarkable degree of reliability with respect to absolute cortical thickness across the groups (lower right graph in Fig. 4). Figure 4 illustrates the mean thickness and standard error within regions across the very mild AD and incipient AD groups, with the OC and mild AD groups shown for comparison.
Further improvements are expected by optimizing the sublayer ratios and the absolute period thickness.
