数字同轴全息显微镜是一种很有前途的高分辨率成像新工具。通过使用乳胶珠,我们证明,如果在光源和CCD相机芯片之间的空间填充高折射率介质,则可以显著增加数值孔径,从而实现分辨率。高折射率介质意味着较短的有效波长,因此激光可以在可见光范围内获得亚微米级的分辨率。(C)2006年美国光学学会。
Digital in-line holographic microscopy is a promising new tool for high resolution imaging. We demonstrate, by using latex beads, that a considerable increase in numerical aperture, and, therefore, resolution can be achieved if the space between a source and a CCD camera chip is filled with a high refractive index medium. The high refractive index medium implies a shorter effective wavelength so that submicrometer resolution can be obtained with laser light in the visible range. (c) 2006 Optical Society of America.
