Abstract:
1. A method of constructing a fluid lens comprising a fluid lens reservoir defined at least in part by one or more sidewalls, the method comprising: establishing a generalized sidewall profile function; converting the generalized sidewall profile function to a plurality of lens sidewall contact angle functions defined by different combinations of sidewall profile parameters, wherein each of the lens sidewall contact angle functions is characterized by a degree of operational linearity between a lens sidewall contact angle and a target lens fluid lateral shift along an x axis; determining respective degrees of operational linearity of the lens sidewall contact angle functions over a range of positions along the x axis by assessing derivative uniformity of each of the lens sidewall contact angle functions within an established slope flatness metric ε; evaluating the respective degrees of operational linearity of the lens sidewall contact angle functions to identify an optimized sidewall profile; and constructing the fluid lens by forming the fluid lens reservoir with at least one sidewall comprising the optimized sidewall profile.
