MitAC update
- Naming convention for images agreed upon 33/45/78-backscan-length-modthresh-datarestorepixels-fov-turret-Z
- Choice of known experimental 78rpm for intial studies - "There's a tear in my beer tonight" by Hoosier Hot Shots and Sally Foster, Damon is searching for clean digital copy and we plan to record it from a turntable
- Platter, record mat and approximate thread match found, longer screws and washplates to be purchased Tuesday from Home Depot to complete microscope stage assembly
- Partial delegation of short-term research responsibilites: Damon (physics of white light interferometry, stitching methods), Simon (physics of vinyl manufacturing/cartridges/lathes, Wikipedia literature update for LBNL etc., complete platter stage assembly), both (familiarization with imaging capabilities to the level of Tom's images and to begin stitching feasibility study)
- Currently capable of achieving images as described by Veeco salesman in tutorial (clear top/bottom groove, no sidewalls), this is partially circumvented by enabling data restore (linear interpolation) but is not of the quality of Tom's VSI images in Ich's powerpoint slides
- the problem appears to be focusing in deep cracks (~30um) rather than post processing since fringe patterns do not appear on sidewalls regardless of tilt, filter, fov, turret, intensity, and fringes appear successfully on top groove and bottom during scan
- ASCII datasets seem to be the choice output format due to options to incorporate post-processing and better than 8-bit resolution, rather than TIFF as previously suggested
