Abstract
We propose an optical tomographic mapping method of nanoparticles based on a light-scattering using a computational ghost imaging (CGI) with multi-wavelength evanescent lights. In general, for optically detecting nanoparticles, there is a requirement of a high-sensitivity measurement because the scattered light from nanoparticles is weak. For solving the problem, we focus on the CGI which allows a high-sensitive measurement by using a correlation and a multiplex effect. Additionally, for permitting a three-dimensional mapping, multi-wavelength evanescent lights are applied to the illumination pattern of the CGI. Numerical calculations and experimental results are shown about the possibility to reconstruct a depth-dependent images.
