Team Cydonia Conceptual Design Review Derek, Dominic, Greg, Kevin, Max, Sarah 9.20.07 Team Cydonia Conceptual Design Review
Mission Overview Two tasks Capture photos for dark current Take CCD video Possible time lapse
Mission Overview Dark Current How a camera works Part 1: Each pixel works like a bucket collecting light Makes a count based on energy The more light energy, the more counts A black picture should have no pixel count But this isn’t true, dark current adds energy -> ups pixel count Dark current is based on thermal energy As long as camera is heated, there is dark current
Mission Overview Dark Current Continued A hot camera will produce a washed out picture:
Mission Overview Dark Current Continued Can reduce dark current by cooling camera Measure dark current by taking black picture Measurement used to subtract dark current from telescope pictures
Mission Overview Dark Current Continued If we can just subtract it, why waste power, weight, and energy to cool it down? Two parts to dark current Average—can be subtracted Random—cannot be subtracted Can still have a washed out picture Can accidentally subtract out faint stars
Mission Overview Video Capture How a camera works Part 2: The Bayer Filter
Mission Overview Video Capture Continued Bayer Filter isolates red, green, and blue pixels Computer determines a true color from average Twice as many green due to eye sensitivity Make the computer work backwards
