Title:
HOLOGRAPHIC IMAGING DEVICE AND DATA PROCESSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/044336
Kind Code:
A1
Abstract:
The present invention provides a holographic imaging device that can be produced as either a transmissive type or a reflection type and capable of achieving a wide field of view at a long operation distance or at ultra-high resolution, and a data processing method therefor. Object light Oj is recorded into a plurality of object light holograms Ij
OR for each incident direction using off-axis spherical-wave reference light R, the object light Oj being generated from an object that is sequentially illuminated with parallel illumination light Qj with varied incident directions θj. The reference light R is recorded into a reference light hologram ILR using inline spherical-wave reference light L that is in line with the object light Oj. An object light wave hologram hj (x, y) and the spatial frequency spectrum Hj (u, v) thereof are produced at the object position for each incident direction using each hologram ILR, Ij
OR. Each spectrum Hj (u, v) is caused to match in an overlapping area to produce a synthetic spectrum HT (u, v) that occupies a wider frequency space, thereby creating a synthetic object light wave hologram hT (x, y) with increased numerical apertures.
