摘要： The present invention is an optical measurement system for measuring a liquid sample within a well. The system comprises a light source configured to transmit light though the well, a detector configured to measure optical signals derived from the transmitted light, and a tunable optical element. The tunable optical element is positioned between the light source and the well. The tunable optical element is operable to shape the light to compensate for distortions induced by a surface of the liquid sample. The detector is preferably located below the well for receiving a forward scatter signal indicative of at least one characteristic of the particles within the liquid sample.

摘要： Directive projection screens described herein are configured to selectively direct incident light depending upon an angle of incidence of the light. Such direction improves projection screen gain. Incident light within an acceptance cone is configured to be presented to a viewer. Light outside of the acceptance cone is directed away from the user or absorbed. As a result of this selectivity and the gain, presentation of images on the directive projection screen is improved in the presence of non-projector light sources.

摘要： Optical systems are provided that include illumination sources, micro-mirror array optical modulators, and an optical element. The micro-mirror array optical modulators can selectively modulate light beams, redirect light by diffraction and reflection, and provide an output modulated light beam that exhibits a diffraction handedness dependent on the spectral bandwidth of the light incident thereupon. The optical element has a color dependent aperture that defines portions of output modulated light beams that are transmitted and remaining portions that are blocked. An efficiency and contrast of each the output modulated light beams acquired by the optical element can be independently determined by a narrow spectral bandwidth of each of the light beams, the spectral characteristics of the color dependent aperture, and the diffraction handedness of the micro-mirror array optical modulators for the associated spectral bandwidth.

摘要： There is provided a fundus imaging apparatus which suppresses generation of a ghost image, and is capable of high-magnification/high-resolution fundus imaging (AO-SLO), and low-magnification/wide-angle fundus imaging for wide-angle monitoring by a compact optical system having high optical performance. In a fundus imaging apparatus which guides light emitted by a light source to an eye to be inspected, through a scanning unit for two-dimensionally scanning a fundus, and obtains a fundus image based on the light reflected by the eye to be inspected, an optical system between the scanning unit and the eye to be inspected is constituted by a plurality of reflecting surfaces. The first reflecting surface from the eye to be inspected is a rotationally asymmetrical aspherical surface.

摘要： An imaging lens includes a lens barrel, a plurality of lens elements and a spacer. The lens elements are disposed in the lens barrel. The spacer is disposed between the lens barrel and one of the lens elements or between two adjacent lens elements. The spacer is ring-shaped and includes an inside layer and two outside layers. The two outside layers are attached on opposite sides of the inside layer, respectively. The spacer has an object-side surface, an image-side surface and a first inner ring-shaped oblique surface. The object-side surface and the image-side surface are formed outside the two outside layers in parallel and oriented toward an object side and an image side of the lens elements, respectively. The first inner ring-shaped oblique surface is formed at an inner periphery of the spacer and connected to at least one of the object-side surface and the image-side surface.
