Lasers & Optics
Applications
SWIR imaging is relevant for numerous
applications across various industries
including defense and surveillance,
machine vision, industrial
automation, quality control, medical
imaging, automation, and for example
augmented reality within the consumer
domain. Taking advantage of the broad
spectrum, Emberion cameras can detect
all the laser range finder wavelengths
(905 nm, 1,064 nm, 1,550 nm, >1,700
nm) providing tactical advantage. With
HDR > 120 dB, surveillance is a prime
application including seeing through
adverse conditions such as smoke, haze,
and snow.
One of the keys areas of application is
in Defense where Emberion's QD sensor
based cameras can be used for surveillance
i.e. in harsh environments (snow,
haze, smoke). In addition to this, a camera
that can detect all the laser wavelengths
for laser range finding and designation
is vital i.e. 905 nm, 1,064 nm,
1,550 nm and beyond 1,700 nm for tactical
advantage. It can support camouflage
detection and using wavelength
>1,850 nm and taking advantage of the
1,920-1,940 nm water peak it can detect
the appropriate contrast level required to
detect objects.
Conclusion
Imagers based on CQD-on-CMOS are
emerging as a competitively performing
and cost-effective alternative to Indium
Gallium Arsenide (InGaAs) currently
dominant in SWIR sensing. The tailorable
spectral range and scalability in
pixel dimensions provide opportunities
for next-level application-specific optimization.
When comparing focal plane
arrays (FPAs), the relevant FoM providing
best like-for-like performance comparison
is NEI, which indicates the
actual sensitivity performance of the
array at a given target frame rate.
Although InGaAs sensors exhibit external
quantum efficiency (EQE) superior
to CQD, and low dark current in the
range of few fA, the NEI performance is
limited by read- out noise typically of
the order of 250 e- for CTIA-based
ROICs. Our preliminary calculations
indicate that the NEI- performance of
Emberion's VGA imager with 20 µm

pixel size exceeds that of benchmark 5
µm-pixel InGaAs imagers.
