to measure/ record an optical setup
what to do when the setup does not actually function
to clean optics
to pick worms.
This week was the first real week in the lab where I could help instead of being lost.
1) Measuring a setup: Hold … Continue reading
As the other new grunt of the VAOL, this first week was spent learning the ropes around the lab. I started out my week watching a laser safety video so I would be allowed to go into the actual lab … Continue reading
As one of the new grunts of VAOL, this first week has progressed appropriately awkwardly, full of disorientation and demonstrations. I think it is appropriate to keep this first post simple, and avoid technicalities.
As I’ve been introduced to the lab, … Continue reading
Most, if not all, studies of thrashing frequencies of swimming frequencies of C. elegans have been conducted using microscopic techniques. Microscopic techniques require microscopic life to remain in a focal plane within microns. Using microscopic techniques, the C. elegans … Continue reading
In the previous post, the reason that only oversampled patterns can be reconstructed was introduced.
The next question is then–how do we construct these patterns and how can we retrieve the phase quantitatively? Here’s a overview of the iterative algorithm that … Continue reading
Before introducing the concept of oversampling, let’s first talk about an effect named “aliasing” that is just as important.
An example of aliasing can be seen in old movies, especially when watching wagon wheels on old Western films. You would occasionally … Continue reading
In physics the phase problem is the name given to the problem of loss of information concerning the phase that can occur when making a physical measurement. The name itself comes from the field of x-ray crystallography, where the phase … Continue reading

“C. elegans has become a favorite model system for the study of development due to the recent discovery that its genetic makeup differs very little from that of a fly, fish, mouse, or human.”
–Professor Greg Hermann
I never actually thought that … Continue reading
