- Title Slide
- Summary
- What is going to be discussed in the presentation
- Basics of wavefront sensing
- what a wavefront is,
- Purpose of what I am doing
- What is an optical differentiation sensor
- diagram and explanation
- prototype
- Comparison between OD and Shack-Hartmann sensor
- OD has better dynamic range, can look at polychromatic sources
- Important to make sure quality of image is the same
- Explanation of Signal to Noise Ratio
- Important to compare different sensors
- Shows how much of original image is preserved
- Equation for the SNR of OD and SH sensor
- From paper by Oti
- Explanation of terms
- Derivation
- Numerical calculation of SNR of both sensors
- Estimation for number of photons and ensemble average
- Actual calculation
- Analysis of numerical calculation
- Oti Graph
- Difference in Airy rings
- Atmospheric turbulence term for Shack-Hartmann sensor
- Graph and explanation
- Centroid error term for Shack-Hartmann sensor
- Graph and Explanation
- Larger project and Deformable mirror
