Abstract
Se describen métodos y sistemas para seguir el enfoque de un sistema de formación de imágenes basado en lentes de enfoque variable ajustable. Un método de ejemplo incluye identificar una posición de enfoque inicial de un ensamblaje de lentes de enfoque variable ajustable y determinar los parámetros de focalización correspondientes a esa posición de enfoque. Los parámetros de focalización se comparan con un modelo de comportamiento de la lente y se determina una nueva posición de enfoque compensada del ensamblaje de la lente para corregir los cambios en el rendimiento del ensamblaje de la lente. También se puede ajustar un rango de barrido de focalización de ventana pequeña, entre las posiciones delantera y trasera, en función del modelo de comportamiento de la lente para identificar mejor la posición de enfoque compensada.
