Alternative Calibration methods of radiometric detectors

The usual way of calibrating detectors or devices is to treat them as black boxes. We measure the response when the device is excited with a well known signal. With this approach we throw away a lot of information that can be used to develop new calibration techniques. In the common European project chipS∙CALe (running from June 2019 – May 2022) we aim to develop self-induced silicon photodiodes capable of calibrating themselves in possibly remote operation. The trick is to exploit the intrinsic quantum properties of photodiodes that each photon generates exactly one electron-hole pair. This is a valid assumption to about 99.9% of common calibration standard photodiodes used in laboratories today when correcting for reflectance
