Abstract: Exemplary thin-film optical devices have first and second layer groups disposed as a layer stack on a substrate. The first layer group comprises a first PPN layer, a first LCP layer, and a first barrier layer all superposed. The second layer group is superposed relative to the first layer group, and includes a second PPN layer, a second LCP layer, and a second barrier layer all superposed. The first and second layer groups cooperate to polarize multiple wavelengths of an incident light flux in a broadband and/or wide-angle manner Each of the layer groups has an alignment layer, a respective liquid-crystal polymer layer, and a barrier layer.

Abstract: A polarization property image measurement device includes: a first radiation unit that radiates light beams in different polarization conditions onto a target object after subjecting the light beams to intensity modulation at frequencies different from one another; a light receiving unit including first photoelectric conversion units that photoelectrically convert the light beams having been radiated from the first radiation unit and scattered at the target object in correspondence to each of the different polarization conditions, and second photoelectric conversion units that photoelectrically convert visible light from the target object; and a processor that detects signals individually output from the first photoelectric conversion units at the different frequencies and differentiates each signal from other signals so as to determine an origin of the signal as one of the light beams; and creates an image of the target object based upon signals individually output from the second photoelectric conversion units.

Abstract: The present invention provides an ellipsometry device and an ellipsometry method whereby measurement efficiency can be enhanced. In this method, an object is illuminated by spherical-wave-like illumination light Q linearly polarized at 45° (S1), and an object light O, being a reflected light, is acquired in a hologram IOR using a spherical-wave-like reference light R having a condensing point near the condensing point of the illumination light Q, and a hologram ILR of the reference light R is furthermore acquired using a spherical-wave reference light L having the same condensing point as that of the illumination light Q (S2). The holograms are separated into p- and s-polarized light holograms IKOR, IKLR, κ=p, s and processed to extract object light waves, and object light spatial frequency spectra GK(u, v), κ=p, s are generated (S3) (S4). Ellipsometric angles ψ(θ), Δ(θ) are obtained for each incident angle θ from the amplitude reflection coefficient ratio ρ=Gp/Gs=tan ψ·exp(iΔ). Through use of numerous lights having different incident angles θ included in the illumination light Q, data of numerous reflection lights can be acquired collectively in a hologram and can be processed.

Abstract: This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.

The display includes a quantum dot backlight module and a first polarizer, wherein the quantum dot backlight module includes a light guide plate, a quantum dot thin film layer, and a backlight. The method obtains the correction spectrum of the quantum dot backlight module, and obtains the true spectrum of the quantum dot backlight module when the first polarizer is arranged on the light exit side of the quantum dot backlight module based on the correction spectrum and the measurement spectrum, that is, the modified spectrum, so as to accurately simulate the chromatic offset phenomenon due to the secondary excitation of the first polarizer, and provide the basis for the quantitative design of the display including the quantum dot backlight module. The present disclosure also discloses a chromaticity calculation method of a display.

Abstract: A combination of a focusing element, and a filtering element which naturally adjusts the cross-sectional area of a beam of electromagnetic radiation passed through the focusing element as a function of wavelength over a specified range of wavelengths, wherein the filtering element is not uniform, but rather varies as a selection from the group consisting of: optical density and/or thickness is greatest near the center thereof; and optical density and/or thickness is smallest near the center thereof; and can demonstrate neutral density characteristics outside the specified range of wavelengths. The combination of a focusing element, and a filtering element can optionally be present in an ellipsometer or polarimeter system.
