Paper Abstract
A novel detector, incorporating e2v's L3 CCD
(L3VisionTM) [1] technology for use in LIDAR (Light
Detection And Ranging) applications has been
designed, manufactured and characterised. The most
critical performance aspect was the requirement to
collect charge from a 120μm square detection area for a
667ns temporal sampling window, with low crosstalk
between successive samples, followed by signal readout
with sub-electron effective noise. Additional
requirements included low dark signal, high quantum
efficiency at the 355nm laser wavelength and the ability
to handle bright laser echoes, without corruption of the
much fainter useful signals.
The detector architecture used high speed charge
binning to combine signal from each sampling window
into a single charge packet. This was then passed
through a multiplication register (EMCCD) operating
with a typical gain of 100X to a conventional charge
detection circuit. The detector achieved a typical
quantum efficiency of 80% and a total noise in darkness
of < 0.5 electrons rms. Development of the detector was
supported by ESA.
