Holographic tomographic microscopy, holographic tomographic image generating method, and holographic data acquisition method for tomographic image

摘要

Holographic tomographic microscopy, holographic tomographic image generating method, and a data acquisition method for holographic tomographic image, and can generate a tomographic image accurately and at high speed. The method comprises a data acquisition step (S1), and a tomographic image generating step (S2 to S7). The data acquisition process, illumination light Q, off-axis spherical wave reference beam R, such as object light O per light of each wavelength lambda ^j by changing the wavelength of the inline spherical wave reference beam L hologram I ^j_OR, I ^j_QR, to get the I ^j_LR. The tomographic image generating step, these holograms, seek a reproduction light wave h ^j of the object light O ^j in the playback surface z = z _P and reproducing light wave c ^j of the illumination light Q ^j. Play lightwave was adjusted phase ^{h j / (c j / |} c j |) of each wavelength are added (j = 1, ··, N ) for obtaining the tomographic hologram _{H P.} Now, ₌ accurate tomographic image without distortion in focus _S P _^| H P _|² is obtained. .FIELD 1
