L3CCD/EMCCD Technology for LIDAR Applications
The L3CCD (Low Light Level)/Electron Multiplying technology is a rather new technology developed by E2V (UK) combining
the CCD capability with the photon counting capability. The detector has been primarily developed for night vision applications
but could have very interesting applications in space lidar remote sensing where very low backscatter signals have to be
detected and photon counting capability is required for the acquisition chain. Such a detector would provide very high quantum
efficiency, as other silicon CCDs associated with quasi-null detection noise. This would improve the Signal to Noise Ratio and
the lidar capabilities, when compared to Accumulation CCDs as proposed for AEOLUS mission. It would furthermore provide
shot-to-shot capability.If the suitability of such a detector, and in particular the amplification process, for lidar application is not
demonstrated, it is then proposed to assess such a devices for generic lidar applications.The concept of such detectors is
suitable for any UV-Visible and NIR lidar. The proposed tasks are : derive detector design requirements for lidar applications;
breadboard and manufacture of CCDs based on EMCCD/L3CCD technology; define, develop and breadboard a set-up for
operating the detector including proximity electronics Integration and Tests; performance consolidation and suitability of the
detector for lidar applications.
Deliverables:
Detector design report Detector breadboard Electronics and set-up to operate the detector Reports on results of assessment
and suitability to lidar applications.

Title:
Ultra-compact medium-resolution spectrometer for land application
The objective of this activity is to develop a linear variable filter elegant spectrometer breadboard. This activity will make use
of the linear variable filter technology developed in a previous TRP contract. The novelty of the concept is to glue a linearly
variable filter glass directly onto the detector array, thus achieving a very compact spectrometer instrument for hyperspectral
medium resolution applications. The linear variable filter coated on a cover glass will be packaged and aligned to a detector
array, which has been already space qualified. The overall assembly of filter and detector will be optically and environmentally
tested.
Deliverables:
Elegant breadboard of a linear variable filter spectrometer in which the filter is directly applied to the detector. The breadboard
will be optically, electronically and environmentally tested.
