Title:
PHASE IMAGING DEVICE AND PHASE IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/172135
Kind Code:
A1
Abstract:
A spatial light modulator 8 is provided on a plane conjugate to a sample plane on which a sample 2 is disposed, and spatially modulates illumination light SILL which illuminates the sample 2 or object light SOBJ which the sample 2 transmits or reflects. A dark field optical system 6 removes non-scattered light components of first object light SOBJ1 influenced by the spatial light modulator 8 and generates second object light SOBJ2. An image sensor 104 records a hologram based on the second object light SOBJ2. A calculation processing device combines complex amplitude information based on a modulation pattern PTN applied to a spatial light modulator 108 with complex amplitude information based on the hologram for the second object light SOBJ2 to obtain a phase distribution due to the sample 2.
