# micro-photogrammetry

## Course Proposal

### Overview
In the wake of COVID-19, CBA has spun up a number of quick response projects to provide effective PPE and medical supplies using our tools at MIT and leveraging the larger fablab community. Fortunate to still have lab access, I have focused on characterizing and testing filter material with various microscopy techniques and building an Filtration Efficiency Testing Appartus ([FETA](https://gitlab.cba.mit.edu/camblackburn/filter_testing)) to measure the pressure drop and filter efficiency of MERV graded materials and common household items. I have been agregating my results into a database documented [here](https://camblackburn.pages.cba.mit.edu/filter_media/). Throughout this process,
