Abstract
Electron-multiplied Charge Coupled Devices (EMCCDs) are used in many astro nomical instruments where they provide much improved signal to noise compared to conventional CCDs. However, the gain provided by electron-multiplication may not be known with precision, leading to errors in the measurements. Several techniques to estimate the gain of EMCCDs are researched and investigated in this work, includ ing some techniques previously only used for microscopy. Investigation and analyses were completed in a simulation environment, in a laboratory environment, and us ing data collected by an astronomical instrument (Galway Astronomical Stokes Polarimeter), where accurate gain estimation of the EMCCD detectors is important for the polarimetry results from the instrument.
