Logarithmic Photo-Converter with Huge Dynamic Range
Summary: This device is capable of measuring optical light levels that may vary from the single photon level up to many orders of magnitude larger illuminations. In fact, the upper range can be almost, apart from practical spatial details, as large as one desires. This device is possible due to the fact that the SiPMs can be exposed to daylight at ...
