A revolution in functional brain imaging techniques is in progress in the field of neurosciences. Optical imaging techniques, such as high-density diffuse optical tomography (HD-DOT), in which source-detector pairs of probes are placed on subjects’

We studied the feasibility of two-photon absorption recording and reflective reproduction for three-dimensional (3D) optical memories by comparison between bulk and super-multilayered media. The basic design of such a super-multilayered structure for

In the field of microoptics, surface-relief diffractive optical elements (DOEs) are of great interest. Their thin film structure makes it possible to produce and integrate them with other optical components. Recent development in microfabrication tec

Blazed reflection diffractive microlenses potentially have many uses. The fabrication accuracy and the optical characteristics of these microlenses can be greatly improved compared with transmission diffractive microlenses. The reflection microlenses

A compact focus sensor constructed with thin film components such as a reflection twin micro-Fresnel lens and a photodetector is proposed. This sensor has a folded optical path and is insensitive to wavelength shift. Theoretical analysis indicates th

The microfabrication of a blazed reflection micro-Fresnel lens (RMFL) using electron-beam writing and dry development is proposed and demonstrated. The electron-beam-written resist film made of polymethyl isopropenyl ketone and an aromatic azido comp

We have developed a diffractive micromachined chopper (DMC) for an IR wavelength of ~10 mum. This device operates mechanically by movable reflection grating beams. It modulates the diffraction efficiency by controlling the displacement of grating bea

Blazed diffractive optical elements (DOEs) were studied for the violet wavelength by electron-beam lithography. By optimizing electron-beam writing parameters and electron-dose distributions, we fabricated eight kinds of grating (period A = 10-0.54 m
