Abstract: A curved mirrored surface (78) is used to collect radiation scattered by a sample surface (76a) and originating from a normal illumination beam (70) and an oblique illumination beam (90). The collected radiation is focused to a detector (80). Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams (70, 90) on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors (78) to restrict detection to certain azimuthal angles.

Abstract: Imaging of a turbid object utilizes interference among the modulation wavefronts (24) of a plurality of modulated light rays (22) propagating through the object by diffusion and having predetermined phases relative to one another. A computer controlled phase and amplitude selecting device, such as a zone plate (34) is used to modulate light rays at appropriate phases in order to obtain constructive interference only at a predetermined portion of the object, including one or more preselected voxels (26). The rays reflected from (or diffusively transmitted through) the predetermined portion are received simultaneously at a detector (16) thus providing simultaneously all the data necessary to describe or image the portion. A single detector (16) element may be used to detect the scattered reflected or transmitted light from the portion and to generate a signal representing the amplitude and phase characteristics for the modulation wavefront, thereby to provide absorption (and other) characteristics descriptive of the portion.

Abstract: Systems and methods for determining one or more properties of a sample are disclosed. The systems and methods disclosed can be capable of measuring along multiple locations and can reimage and resolve multiple optical paths within the sample. The system can be configured with one-layer or two-layers of optics suitable for a compact system. The optics can be simplified to reduce the number and complexity of the coated optical surfaces, etalon effects, manufacturing tolerance stack-up problems, and interference-based spectroscopic errors. The size, number, and placement of the optics can enable multiple simultaneous or non-simultaneous measurements at various locations across and within the sample. Moreover, the systems can be configured with an optical spacer window located between the sample and the optics, and methods to account for changes in optical paths due to inclusion of the optical spacer window are disclosed.

Abstract: An optical module includes: a measuring device including a measuring portion that measures light reflected at a measurement position of a measurement target, a light source that radiates light onto the measurement position in a direction crossing a measurement optical axis oriented from the measurement position to the measuring portion, and a window through which light incident on the measuring portion passes; and a shutter that opens and closes the window of the measuring device. The shutter is provided with a reference object disposed closer to the measuring portion side than the measurement position on the measurement optical axis, on a face of the shutter facing the measuring portion when closing the window, and the optical module includes a light guide that guides the light from the light source to the reference object when the window is closed by the shutter.

Abstract: Contrary to conventional wisdom, which holds that light-emitting diodes (LEDs) should be cooled to increase efficiency, the LEDs disclosed herein are heated to increase efficiency. Heating an LED operating at low forward bias voltage can be accomplished by injecting phonons generated by non-radiative recombination back into the LED's semiconductor lattice. This raises the temperature of the LED's active rejection, resulting in thermally assisted injection of holes and carriers into the LED's active region. This phonon recycling or thermo-electric pumping process can be promoted by heating the LED with an external source (e.g., exhaust gases or waste heat from other electrical components). It can also be achieved via internal heat generation, e.g., by thermally insulating the LED's diode structure to prevent (rather than promote) heat dissipation. In other words, trapping heat generated by the LED within the LED increases LED efficiency under certain bias conditions.

Abstract translation: 与传统观念相反，认为应该将发光二极管（LED）冷却以提高效率，因此本文公开的LED被加热以提高效率。 加热在低正向偏压下工作的LED可以通过将非辐射复合产生的声子注入到LED的半导体晶格中来实现。 这提高了LED的主动抑制的温度，导致热辅助将空穴和载体注入LED的有源区域。 可以通过用外部源（例如来自其他电气部件的废气或废热）加热LED来促进该声子再循环或热电泵送过程。 也可以通过内部发热来实现，例如通过将LED的二极管结构隔热来防止（而不是促进）散热。 换句话说，LED内的LED产生的热量会在某些偏压条件下提高LED的效率。
