Photon Counting Method Extends Linear Dynamic Range
- 总结
- Researchers at Purdue University have developed a simple photon counting method that provides seven orders of magnitude in linear dynamic range for a single photomultiplier tube detector. This method acquires data by using discriminator-based event counting electronics to measure the count output of a detector. In addition, it bridges an existing gap in maintaining quantitation over measurements with high contrast and has potential application in microscopy and spectroscopy.

- *Abstract
-
- *Background
- Photon counting is a well-established method for detecting low intensity light. However, conventional approaches for photon counting suffer from nonlinearities at high count rates. Several strategies have been adopted for improving the linear dynamic range, but suffer from issues, such as long analysis times and sensitivity differences between instruments.
