The metalens includes a first region that has a plurality of microstructures disposed therein to concentrate terahertz waves; and a second region that is a region that surrounds the first region and that is a region different from the first region, in which in a case where terahertz waves having a wavelength of 0.3 mm, a wavelength of 1 mm, and a wavelength of 3 mm are incident, assuming that a wavelength having a highest light concentration efficiency is a wavelength X, a transmittance of the terahertz waves having the wavelength X in the first region is a transmittance T1, and a transmittance of the terahertz waves having the wavelength X in the second region is a transmittance T2, the transmittance T2 is lower than the transmittance T1.

Abstract: A hologram image of an object is acquired in a state where the object is accommodated in a concave portion provided in a container with a bottom surface of the concave portion being curved. A phase image is generated from the hologram image. Processing of subtracting a phase component derived from a polynomial indicating a shape of the bottom surface of the concave portion from the phase image is performed to acquire a processed phase image.

Abstract: A holography apparatus 10 includes an optical system 200 that forms an interference image due to interference between object light L1 and reference light L2. The optical system 200 includes a retarder 30 that is disposed on an optical path of the object light or the reference light, and a rotation mechanism 31 that rotates the retarder 30 with an optical axis of the object light L1 or the reference light L2 as a rotation axis. The holography apparatus 10 includes an imaging unit 40 that captures the interference image, a control unit 50 that derives an evaluation value for the interference image captured by the imaging unit 40 and controls a rotational position of the rotation mechanism 31 based on the evaluation value.
