Solution Overview

Problem

Segmented arrays, such as micromirror arrays, face challenges in controlling hundreds or thousands of elements with multiple degrees of freedom, requiring complex and cumbersome user-side translation of optical surfaces into element-level commands, which is difficult and inefficient.

Innovation Solution

A system that includes a non-transitory computer-readable medium to store a mapping between subapertures and adjustable optical elements, allowing users to specify high-level commands that are translated into element-level commands, with a user interface module to update mappings and a command generation module to generate element commands based on subaperture properties, considering physical and environmental limits.

Solution Approach 1:

The patent segments the control system into distinct functional layers: a user-friendly interface that accepts high-level optical surface specifications and an automated command generation module that handles the complex translation to element-level commands. This segmentation allows users to operate the system without needing detailed knowledge of the underlying segmented array mechanics, while the system maintains precise control through automated calculations.

Solution Approach 1:

The patent implements a dynamic command generation system that automatically adapts element-level commands based on the specific optical surface specification and the individual positions of segmented array elements. Rather than applying static identical commands to all elements, the system dynamically calculates optimal commands for each element, enabling high adaptability while maintaining manageable system complexity through automated processing.
