Task Assignments

New tasks are in red.

Completed Tasks

  • ADR & CAH: Layout and tolerancing of transmissive optical system
  • ADR & CAH: Use tolerancing results to assign image quality and stability budgets by component
  • XS: Initial studies of achievable stability
    • Replaced by new task below
  • MF: Thermal analysis of camera in box
    • Follow-on task below

High Priority Tasks

  • MF: Determine minimum size of camera enclosure
  • MF & ADR: Use camera enclosure size to refine reflective and transmissive layouts
  • ADR: Final layout/stability budgets for refined layouts: one reflective and one transmissive
  • XS: Conceptual design of unadjustable dichroic mount
  • XS: Model effect of temperature gradient on stability of dichroic in above mount

  • DFB: Write down initial latency and frame rate requirements with brief justification
    • Calculate for 40Hz bandwidth requirement as well as 50Hz goal
  • JSY: Define software components and inter-component dataflows (hardware-independent)
  • JSY: Ask Chris Mayer for field rotation rate
    • Sent query, no reply yet

Medium Priority Tasks

  • MF: Thermal modelling of camera enclosure to refine derived requirements
  • MF: Look for missing derived requirements using N^2 diagram
  • TBA: Calculate seasonal focus change

  • EBS: Look for 1U or 2U computers with 2 PCI slots drawing < 150W

Low Priority Tasks

  • ADR: Dialogue with OAP manufacturer re referencing to optic axis of finished component
