The quality of microscopy imaging is often degraded by sample-induced aberrations. Adaptive optics (AO) is a standard approach to counter such aberrations. We present two novel implementations of sensor-based conjugate AO, as well as the wavefront sensing techniques developed for these implementations. In both implementations, we address the key challenge of developing wavefront sensors that are capable of operating with uncollimated light, which exhibits large diverging angles and may arbitrarily distribute as well. We show that the conjugate AO implementations and their wavefront sensing techniques are not only robust, well-suited for video-rate imaging, but also provide large corrected field of view.
