    Abstract: 一种亮度校正方法及光学检测系统。亮度校正方法应用于光学检测系统中。光学检测系统包含单光源照射器以及探针卡。单光源照射器用以朝向探针卡照射。探针卡具有多个检测位置。亮度校正方法包含:以感测芯片透过多个扩散片其中之一依序在检测位置量测亮度;以感测芯片在检测位置其中之一依序量测扩散片的透明度;以及筛选透明度中较大者所对应的扩散片并分别设置于亮度中较小者所对应的检测位置上方,并筛选透明度中较小者所对应的扩散片并分别设置于亮度中较大者所对应的检测位置上方。借此,根据本发明的亮度校正方法所制造的光学检测系统将可有效地降低光源均匀度、扩散片偏差度与不同检测位置所造成的检测偏差。

    Abstract: Disclosed is a method for correcting the temperature sensitivity of the amount of light L emitted by a light emitting diode (LED) and measured in a light detector, said LED being operated in a pulsed mode with an essentially constant pulse duration tP. According to the inventive method, a predetermined parameter X that has a predetermined ratio to the temperature T of the LED is used while a corrective factor K is determined from said parameter X, preferably using a calibration table, most preferably a closed, predetermined function, with the aid of which the measured emitted amount of light L is corrected by the temperature-dependent variations of the emitted amount of light. The parameter X is determined from at least two output signals of the LED which are correlated in a predetermined manner.

    Abstract: Optical sensing systems having improved vibration cancelation, and methods of achieving improved vibration cancelation. In one example, an optical sensing system (200) includes an optical sensor (210) configured to produce an unprocessed sensor output signal (215) representative of a response of the optical sensor to at least an optical signature of interest and a local vibration excitation, a reference sensor (220) configured to provide a reference signal responsive (225) to the local vibration excitation, and a controller (260), including an adaptive digital filter (230), coupled to the optical sensor and to the reference sensor, and configured to receive the reference signal and to adjust one or more coefficients of the adaptive digital filter to minimize coherence between a residual signal (255) and the reference signal, the residual signal being a difference between the sensor output signal and a filter output signal (235) from the adaptive digital filter.
