Canada-France-Hawaii TelescopeObservatory Automation Project:
Audio and Video Management
Project by: Amber ImaiMentors: Tom Vermeulen & Bill Cruise
Advisor: Sarah GajadharCanada-France-Hawaii Telescope
Home Institution: University of Hawaii at ManoaUniversity of California Santa Cruz, Center for Adaptive Optics (CfAO)
Akamai Internship Program, Summer 2008
Overview
• OAP Design/Objective
• My Role in the OAP
• Work in Progress
• Concluding Statements
OAP Objective(adapted from the OAP Detailed Design, Audio and Video)
• Technical Advances and Observatory Efficiency
• No One at Summit• Easier Work Environment• Mechanical Failure• Solution:
– Need to monitor and remotely control observatory systems
– Can be done through sensors, programmable logic controllers, and WEBCAMS
What is in Progress for the OAP
• Software Infrastructure
• Remote Control of Mirror Cover and Cooling Systems, Telescope Control System, and Dome Shutter (to name a few)
• AUDIO and VIDEO MONITORING
My Role in the Project
• Creating the Audio Video Recording Server– Learn and Understand Linked Lists, Pointers,
Arrays, Strings, and Forked Processes
• Learn about Axis webcams– Axis 214– Axis 207

Work in Progress
• Addition of more cameras• Updating the camera webpage• Other sections of the OAP• Fully Remote Observing
Concluding Statements
• The OAP now has a specially designed server that will record and manage it’s space
• Store data for approximately 1 week
• AV Server COMPLETE!
