Computational imaging with SPADs at SWIR wavelengths
18:00 - 18:20
Martin Laurenzis, Stephane Schertzer, Emmanuel Bacher and Frank Christnacher Single Photon Counting Avalanche Diode (SPAD) sensors can be driven with reverse bias voltages beyond the breakdown point to count single photon events by triggering an avalanche effect. The event time can be read out with sub-nanosecond to a few 10 picosecond precision. Thus, SPAD sensors have the potential to revolutionize optical sensing by combining high sensitivity and high timing precision, and they can be used for computational imaging. In our experiments we used InGaAs SPAD devices as gated single diodes as well as 32x32 array detectors
to perform active imaging at a laser wavelength of 1.5 µm."
