Low-light imaging and camera quantum efficiency and noise considerations
In this talk I will present and discuss key properties of imaging cameras including their sensitivity and applicability for low-light imaging experiments. Parameters like quantum efficiency (QE) and noise are often used in various non-imaging contexts and may lead to some confusion as to what extent they influence the image acquisition process and its outcome. I will address the QE and several types of noise associated with charge-coupled devices (CCDs), electron-multiplying CCDs (EM-CCDs) and scientific-grade complementary metal–oxide–semiconductor (sCMOS).
Prior to joining Andor Technology I worked at Max-Planck Institue for biophysical chemistry in Goettingen, Germany. While there, I studied SNARE protein- and calcium-dependent membrane fusion in neuronal cells in labs of Erwin Neher and Reinhard Jahn. Following a couple of years as an imaging suite supervisor in the Jahn lab and a brief postoc, I went to Belfast and joined Andor as imaging applications specialist where I worked with users of camera in the fields of astronomy, BEC, biomedical imaging, neutron tomography and X-ray.
