  • Derive and specify requirements for the image acquisition chain components based on system-level needs
  • Specification of readout electronics hardware.
  • Specification of FPGA firmware for detector control and video chain interfacing.
  • Interface definition with onboard data handling systems.

• Procurement & Technical Follow-Up
  • Provide technical support during procurement of image sensors and related electronics.
  • Manage supplier technical follow-up and ensure compliance with specifications.

• Laboratory Activities & Validation Test
  • Support the integration and bring-up of the video acquisition subsystem in laboratory environments.
  • Lead the characterization of image sensors and acquisition chain performance.
  • Define and specify OGSE/EGSE for sensor testing.
  • Develop detailed test plans and measurement protocols.
  • Execute test campaigns in ISO-8/ISO-5 cleanroom environments.
  • Implement structured image processing pipelines for data analysis.
  • Generate comprehensive performance test reports.

• Integration & Support
  • Support integration of optical sensors into focal planes and interfacing with front-end electronics.
  • Provide technical assistance to manufacturing and AIT teams for sensor handling and operation.

• Documentation & Reviews
  • Prepare technical documentation for internal and external reviews.
