Abstract: A fiberized single photon sensitive spectrometer on a 32-channel PMT sensor is highly sensitive with broad detection dynamic range. The spectrometer enables accurate and high speed detection, identification and analysis of biological samples labeled with multiple fluorescent markers, such as compositions of multi-color fluorescence signals or radiation emitted by multiple fluorescence dyes. A fiberized optical input of the spectrometer allows an easy and efficient coupling to any measurement system based on fiber collection of the analyzed fluorescence. The spectrometer provides highly accurate DNA sequencing. A 32 channel PMT single photon detector has a detection dynamic range of more than 20 bits and has a frame rate of about 3300 frames per second. The dynamic range of the detector's pixels reaches 108 photocounts per second.

Abstract: Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth, etc. dimension—rather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wave-length, polarization state, or one or more spatial dimensions—or indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these, as well as a gigahertz wavefront sensor.
Abstract translation: 多个电子或光学图像以条纹光学系统提供，例如通过使用多个狭缝而不是传统的单个狭缝，以获得第三，第四等尺寸，而不仅仅是传统的两个，即范围或时间 和方位角。 因此，这样的附加尺寸或尺寸被并入要划线的光学信息中，从而被时间分辨。 增加的尺寸可以采取非常宽的形式范围中的任何一种，包括波长，极化状态或一个或多个空间维度，或实际上实际上可以施加到探测光束上的任何光学参数。 所产生的功能显着地包括激光雷达光谱，荧光分析，偏振测量，分光偏振测量及其组合的几种新形式，以及千兆赫兹波前传感器。

Abstract: A photomultiplier tube comprises an evacuated envelope having a photoemissive cathode therein. A cage assembly including an anode and a plurality of closely spaced dynodes are within the envelope. The anode has at least one support rod. Each of the dynodes has a pair of dynode tabs formed in the ends thereof. A pair of dynode support spacers having a plurality of stress isolation apertures and electrode support apertures formed therethrough are provided for supporting the dynodes and the anode. The dynode tabs and the anode support rod extend through the electrode support apertures. A plurality of deformable stress isolation eyelets comprising a tubular shank with a flare formed in one end of the shank are disposed within a different one of the stress isolation apertures. The flare diameter is greater than the diameter of the stress isolation apertures thereby retaining the eyelets within the apertures. A second end of the tubular shank, opposite the flared end, extends outwardly from the dynode support spacers. The outwardly extending end portion is crimped to lock the eyelets within the stress isolation apertures. Nickel leads are provided for flexibly interconnecting the crimped end portion of a different one of each of the eyelets to one end of each of the dynodes and to one end of the anode support rod. A stem closes one end of the envelope. A plurality of relatively stiff cage assembly support leads extend through the stem and are welded to the crimped end portion of the eyelets thereby firmly securing the cage assembly to the support leads and indirectly connecting the support leads to the dynodes and the anode.
