In the present invention, a tomographic image can be accurately generated at high speed in a holographic microscope, a holographic (tomographic) image generation method, and a method for acquiring data for a holographic (tomographic) image. The present method includes a data acquisition process (S1) and a tomographic image generation process (S2 through S7). In the data acquisition process, holograms (Ij OR, Ij QR, Ij LR) of object light (O) and so forth are acquired for each light with a wavelength (λj) by changing the wavelengths of the illumination light (Q), off-axis spherical wave reference light (R), and inline spherical wave reference light (L). In the tomographic image generation process, a reproduced light wave (hj) of the object light (Oj) and a reproduced light wave (cj) of the illumination light (Qj) on a reproduced surface (z = zP) are acquired from these holograms. A reproduced light wave (hj / (cj / |cj|) with adjusted phase is added for each wavelength (j = 1, ⋅⋅, N) to acquire a tomographic hologram (HP). From this, a focused tomographic image SP = |HP|2 which is accurate without distortion can be acquired. |
