<P>PROBLEM TO BE SOLVED: To substantially remedy the problem in a digital holography device that it is difficult to increase accuracy of reproduced image and that a calculation amount associated with generation of reproduced image becomes enormous. <P>SOLUTION: A digital holography device generates a reproduced image of a subject M through: a step for exposing an imaging surface Sp of an imaging part 2 to object light Lm, which is emitted from the subject M exposed to light L, and reference light Lr; and a step for applying predetermined arithmetic processing to hologram image data Dp obtained by letting the object light Lm interfere with the reference light Lr. The digital holography device is configured to comprise: object light imaging means F1 that includes an optical system 3 for generating an imaging point Pf of the object light Lm near the imaging surface Sp; and reproduced image generation means F2 that uses only a pixel relating to an imaging element within a region A of the object light Lm, to which the imaging surface Sp is exposed by the object light imaging means F1, to generate the reproduced image of the subject M at the imaging point Pf. <P>COPYRIGHT: (C)2012,JPO&INPIT |
