Invited Seminar - CMOS SPAD Arrays for Display Metrology

Research output: Contribution to conferencePaper


Photo-detectors capable of detecting and processing single photon events have been around for some time. The photomultiplier tube is more than 80 years old.
Solid state photomultipliers have come of age in the 21st century - sometimes called Single Photon Avalanche Diodes (SPADs) or, if built on a silicon substrate, Silicon Photo-Mulitpliers (SiPM). Recent SPAD arrays are compatible with advanced CMOS fabrication processes and comprise substantial numbers of pixels in a 2-D array and are capable of delivering medium definition images at very high frame rates. Amongst many other applications, advanced CMOS SPAD arrays have significant potential in the field of Display Metrology. This seminar will introduce CMOS SPAD technology and illustrate its application in characterising some useful parameters of OLED microdisplays.
