Adaptive optics

Optical design and preliminary results of NEW EARTH, first Canadian high-contrast imaging laboratory test bench

We present a bench optical design for the first Canadiana test-bed NEW EARTH.

Upgrading the Gemini Planet Imager calibration unit with a photon counting focal plane wavefront sensor

We present a new second stage speckle-correction solution for the Gemini Planet Imager (GPI).

Megapixel Adaptive Optics: Towards Correcting Large-scale Distortions in Computational Cameras

We demonstrate an adaptive optics system for regular cameraswith unprecedented capability to sense and correct large distortions.

Ultra-High Resolution Coded Wavefront Sensor

We introduce a Coded Wavefront Sensor that provides high spatio-temporal resolution using a simple masked sensor, under white light illumination.
