In the algorithm, a camera calibration based on partial orthogonality is performed in order to retrieve multiple pinhole cameras.
I can imagine bemused tourists staring at pinhole projections of a bespotted Sun and remarking on the smallness of Venus, and gangs of students and amateur astronomers chattering jargon into tape recorders, clicking off exposures on digital cameras that are posted almost immediately on the Web.
Multiple pinhole collimators should also be better adapted.
Rapid advances in SPECT, including the use of multiple pinhole collimators, allow high-resolution imaging to less than 1 mm.
Participants with VA <6/18 in either of the eyes were re-assessed using a multiple pinhole occluder.
Subjects with a VA of <6/12 (0.3 logMAR) in either eye were reassessed using a multiple pinhole occluder.
Sadly, the techniques of pinhole projection or using eclipse glasses are useless for this event because of Mercury's small size.
Other options involve using colanders to make multiple pinholes or using specifically designed eclipse viewing glasses.
Please remind your viewers every day until the eclipse on Monday that they MUST wear eclipse glasses to look at the sun directly...or use pinhole projection to view the eclipse.
So, along North America's Atlantic Coast, interested viewers (using proper viewing devices, such as pinhole projection or #14 welders glass) will only see the dark disk of the moon exiting the sun's face at sunrise.
