Web-30 degrees to +30 degrees or a total of 60 degrees. The FWHM is 60 degrees. The plot on the right has a higher maximum light intensity, 15 units. Taking the full width of the plot at 7.5 intensity units, one gets 28 degrees, the FWHM. The larger FWHM value describes a wider beam spread, corresponding to more light diffusion. WebApr 11, 2024 · The FWHM improved from 1.47 to 0.59 mm, 1.76 to 0.83 mm, 1.73 to 0.67 mm and 1.94 to 1.39 mm, respectively. The control case had the point target at a smaller depth due to the lack of tissue layer and was expected to, therefore, have lower FWHM and additionally had the longest sweep (72 vs. 41, 51 and 52 mm, respectively).
