Detector (IMAGE) Optica Caption The researchers used an InGaAs detector with a very high frame rate to acquire a sequence of images of solar panels as a modulated electric current was applied. The very fast imaging speed available from this detector allowed more changes between the images in the sequence to be distinguished.
