The equation of dynamic range of Shack Hartmann sensor is: $\theta_{max} = \frac{\Delta s_{max}}{F} = \frac{d/2}{F}$ $$d$$ is the lenslet diameter. $$F$$ is the focal length of lenslet. Measurement sensitivity is $\theta_{min} = \frac{\Delta s_{min}}{F}$ The trade-off between the dynamic range and measurement sensitivity of a SHWS is: Increasing the dynamic range results […]
