This paper describes a single-chip InGaAs SWIR camera with more than 120dB instant operational dynamic range with an
innovative CMOS ROIC technology, so called MAGIC, invented and patented by New Imaging Technologies. A 320x256-
pixel InGaAs 25μm pitch photodiode array, designed and fabricated by III-Vlab/Thales Research & Technology(TRT), has
been hybridized on this new generation CMOS ROIC. With NIT's MAGIC technology, the sensor's output follows a precise
logarithmic law in function of incoming photon flux and gives instant operational dynamic range (DR) better than 120 dB.
The ROIC incorporates the entire video signal processing function including a CCIR TV encoder, so a complete SWIR
InGaAs camera with standard video output has been realized on a single 30x30 mm2 PCB board with ¼ W power
consumption. Neither TEC nor NUC is needed from room temperature operation. The camera can be switched on and off
instantly, ideal for all the portable battery operated SWIR band observation applications.
The measured RMS noise and FPN noise on the prototype sensor in dark conditions are 0.4 mV and 0.27 mV respectively.
The signal excursion from pixel is about 300mV over the 120 dB dynamic range. The FPN remains almost constant over the
whole operation dynamic range. The NEI has been measured to be 3,71E+09 ph/s/cm2 with 92 equivalent noise photons at
25Hz frame rate, better than the same architecture of InGaAs photodiode array hybridized on an Indigo ROIC ISC9809 with
a pitch of 30 μm for which a readout noise of 120 electrons is observed.
