Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

    • To solve the lighting issue a beam splitter would work well, that way the light can be directed straight onto the widow and would not get in the way of the camera- In person

Risks and Areas of Concern

    • Camera mounts- how to fit the camera into the center with flexures.

    • Lighting Mounts- where and how

    • Mirror mounts- placement and rigidity. Make sure vibration doesn't break the mirror.

Resources or Information Required but not Available

Schedule

    • Beginning of the fabrication phase, all team members reporting to the machine shop and work space whenever possible.

    • Update Gantt chart.
