User Manual for D7100 and MATLAB Code Associated With Imaging Particulates

Document #:

LIGO-T1400515-v5

Document type:

T - Technical notes

Abstract:

This document contains the step by step procedure on how to use a Nikon D7100 with an AF Micro Nikkor 200mm 1:4 D lens and 2x Teleconverter to take images of the optics in aLIGO and process these images using MATLAB code I wrote. MATLAB counts the number of particles there are on the surface of the optic and measures their various sizes, providing accurate and immediate information about the contamination on the optics. The following are also included in this document: the code to process the images, the code to calculate resolution, and a test image of a 3 inch optic.
