Compact, low dispersion, and low aberration adaptive optics scanning system

摘要

An adaptive optics scanning system using a beam projection module with four or more axes of motion that can project and control the position and angle of a beam of light to or from an adaptive optics element. The adaptive optics scanning system is compact in size, overcoming the challenges of a traditional lens and mirror based pupil relay design. The adaptive optics scanning system has little to no dispersion, chromatic aberration, and off-axis aberration for improved optical performance. The system and methods for calibrating and optimizing the system are described. A modular adaptive optics unit that scans and interfaces an adaptive optics element is described.

1. An adaptive optics scanning system comprising:
an emission source for generating light, the light being directed through the adaptive optics scanning system to a sample; one or more adaptive optics element(s), the adaptive optics element(s) affecting the wavefront, affecting the intensity, or affecting both the wavefront and intensity of the light; a beam projection module, the beam projection module operating with four or more axes of motion and controlling an angle and position of the light to preferentially interface the adaptive optics element by creating or accommodating a beam pivot point at or near the adaptive optics element(s) while scanning the light across the sample; a controller for controlling motion trajectories of the axes in the beam projection module; sample delivery optics, the sample delivery optics appropriately conditioning and directing the light to the sample; one or more detector(s), the detector(s) measuring light from the sample.
