摘要： A photo-detector generated signal is measured as a sample set comprising a long signal and a short signal. The short signal is scaled to the value of the long signal if the long signal exceeds a dynamic range associated with the photo detector. In one embodiment, the short signal is obtained during a short time interval that is at the approximate middle of a long time interval such that the short and long intervals share a common median time value. Given such symmetry, an approximately linear signal yields a proportionality parameter between the long and short signals thereby allowing the short signal to be scaled. The proportionality parameter facilitates determination of an integration independent component of the photo detector signal that should be removed from the measured long and short signals before scaling. A plurality of sample sets can also be processed such that each sample set overlaps with its neighboring sample set, thereby increasing the effective number of sample sets.
摘要翻译：光检测器产生的信号被测量为包括长信号和短信号的样本集。如果长信号超过与光电检测器相关联的动态范围，则短信号被缩放到长信号的值。在一个实施例中，在短时间间隔内获得短信号，该短时间间隔在长时间间隔的大致中间处，使得短间隔和长间隔共享公共中值时间值。给定这种对称性，近似线性的信号在长信号和短信号之间产生比例参数，从而允许短信号被缩放。比例参数有助于确定光电探测器信号的积分独立分量，该分量在缩放之前应从测量的长信号和短信号中去除。也可以处理多个样本集，使得每个样本集合与其相邻样本集重叠，从而增加样本集合的有效数量。

摘要： An oximeter for measuring oxygen saturation in arterial blood includes a light source for projecting light to a body member to be measured, a light responsive circuit for receiving the light which has transmitted through said body member and for generating at least first, second and third signals at three different wavelengths, and a calculator for calculating at least first SaO.sub.2 data using first and second signals and second SaO.sub.2 data using first and third signals. It is detected whether or not a difference between the first and second SaO.sub.2 data is within a predetermined level. When the difference is within the predetermined level, it is assumed that the first and/or second SaO.sub.2 data are valid, but if not, they are assumed as invalid.

摘要： To provide for more reliable determination of resistance of sample surfaces to light and weather influences, test apparatus is equipped with a radiation-measuring device. A portion of radiation used for testing is guided to the measuring device, by quartz guides, spectrally dispersed, and measured as to intensity and/or dosage in one or several pre-selected spectral regions. Tests may use natural or artificial radiation, and a measuring device may be stationary or movable relative to a radiation source.

摘要： Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.

摘要： An optical inspection system or tool can be configured to inspect objects using dynamic illumination where one or more characteristics of the illumination is/are adjusted to meet the inspection needs of different areas. For example, the illumination intensity may be increased or decreased as the tool inspects areas of memory and periphery features in a wafer die. In some embodiments, the adjustment can be based on data obtained during a pre-inspection setup sequence in which images taken based on illumination with varying characteristics are evaluated for suitability in the remainder of the inspection process.

摘要： An inspection system and method is provided herein for increasing the detection range of the inspection system. According to one embodiment, the inspection system may include a photodetector having a plurality of stages, which are adapted to convert light scattered from a specimen into an output signal, and a voltage divider network coupled for extending the detection range of the photodetector (and thus, the detection range of the inspection system) by saturating at least one of the stages. This forces the photodetector to operate in a non-linear manner. However, measurement inaccuracies are avoided by calibrating the photodetector output to remove any non-linear effects that may be created by intentionally saturating the at least one of the stages. In one example, a table of values may be generated during a calibration phase to convert the photodetector output into an actual amount of scattered light.
