AI Article Synopsis
- Nulling interferometry is a technique aimed at directly detecting Earth-like planets, requiring precise control of beam intensity and phase.
- A new device called the Adaptive Nuller uses a deformable mirror to adjust these parameters across a wavelength range of 8 to 12 micrometers.
- This system achieved impressive performance, producing rejection ratios of 82,000:1 over a bandwidth of 3.2 micrometers, focusing on wavelengths around 10 micrometers.
Article Abstract
Nulling interferometry has been proposed for the direct detection of Earth-like planets. Deep stable nulls require careful control of the relative intensity and phase of the beams that are being combined. We present a novel compensator, the Adaptive Nuller, that corrects the intensity and phase as a function of wavelength from 8 to 12 microm using a deformable mirror. This compensator has been used to produce rejection ratios of 82,000:1 over a bandwidth of 3.2 microm centered around 10 microm.
