Superior Quantitative EMCCD Imaging #1 Bias stability – The imaging stability of the EMCCD camera can be assessed by measuring its output with no light falling on the sensor and measuring the slope of the average intensity. The slope of the average intensity value of a 200 frame sequence (where y=mx+b of the least squares fit) is measured. #2 Gain stability – The actual amount of EM Gain applied on each image in a stream of images can vary depending on many electrical engineering factors. The slope of the average intensity value of a 200 frame sequence (where y=mx+b of the least squares fit)...
