Signal processing device and photodetection device

Номер: US20120018621A1
Автор: Hiroo Yamamoto, Makoto Kobayashi, Seiichiro Mizuno
Принадлежит: Hamamatsu Photonics KK

In a signal processing device of an embodiment, an integration circuit accumulates a charge from a photodiode in an integrating capacitor element, and outputs a voltage value according to the amount of charge. A comparator circuit, when the voltage value from the integration circuit has reached a reference value, outputs a saturation signal. A charge injection circuit, in response to the saturation signal, injects an opposite polarity of charge into the integrating capacitor element. A counter circuit performs counting based on the saturation signal. A holding circuit holds the voltage value from the integration circuit. An amplifier circuit outputs a voltage value that is K times (where K>1) larger than the voltage value held by the holding circuit. An A/D converter circuit sets a voltage value that is K times larger than the reference value as the maximum input voltage value, that is, a full-scale value, and outputs a digital value corresponding to the voltage value from the amplifier circuit.

Systems and methods for temporal multiplexing x-ray imaging

Номер: US20120057678A1
Автор: Guohua Cao, Jian Zhang, Jianping Lu, Otto Zhou
Принадлежит: UNC

The present subject matter relates to systems and methods for temporal multiplexing x-ray imaging of dynamic objects with high temporal resolution and fast imaging speed. A pulsed x-ray beam can irradiate an object undergoing a range of motion such as a cyclic motion. Multiple x-ray images can be acquired at different phases within a single motion cycle or range of the object. The multiple x-ray images can be demultiplexed to produce an individual phase image. Compared to sequential imaging, temporal multiplexing x-ray imaging can achieve high temporal resolution of dynamics object in multiple phases with imaging time comparable to that of a single phase. Temporal multiplexing x-ray imaging can thus be applied to a wide variety of applications, including biomedical imaging and industrial non-destructive testing.

Effects of undesired infrared light are reduced in an imaging system using an infrared light source. The desired infrared light source is activated and a first set of imaging data is captured during a first image capture interval. The desired infrared light source is then deactivated, and a second set of image data is captured during a second image capture interval. A composite set of image data is then generated by subtracting from first values in the first set of image data corresponding second values in the second set of image data. The composite set of image data thus includes a set of imaging where data all infrared signals are collected, including both signals resulting from the IR source and other IR signals, from which is subtracted imaging in which no signals result from the IR course, leaving image data including signals resulting only from the IR source.

Принадлежит: FEI COMPANY

To avoid reset noise in a CMOS chip for direct particle counting, it is known to use Correlative Double Sampling: for each signal value, the pixel is sampled twice: once directly after reset and once after an integration time. The signal is then determined by subtracting the reset value from the later acquired value, and the pixel is reset again. In some embodiments of the invention, the pixel is reset only after a large number of read-outs. Applicants realized that typically a large number of events, typically approximately 10, are needed to cause a full pixel. By either resetting after a large number of images, or when one pixel of the image shows a signal above a predetermined value (for example 0.8×the full-well capacity), the image speed can be almost doubled compared to the prior art method, using a reset after acquiring a signal. 1. A method for acquiring data with an image sensor , the sensor showing a multitude of pixels , the sensor using a reset to bring the pixels to a predetermined state , the method comprising:resetting the voltage of a pixel;reading the voltage of the pixel a first time, resulting in a first read-out value for the pixel;reading the voltage of each pixel a second time, resulting in a second read-out value for the pixel; anddetermining a first signal by subtracting the first read-out value from the second read-out value of the pixel;reading the voltage of the pixel a third time, resulting in a third read-out value;between reading the voltage of the pixel a second time and reading the voltage of the pixel a third time no reset occurs; anddetermining a second signal by subtracting the second read-out value from the third read-out value.2.
