High Contrast Imaging at 3-5 microns
Abstract
The 6.5 m MMT, with its integrated deformable secondary, is an ideal platform for carrying out high contrast diffraction-limited imaging in the 3-5 micron wavelength regime. We have developed a dedicated camera for this purpose that can operate with high efficiency at both the L' and M atmospheric windows. In addition we have demonstrated an approach to diffraction suppression, using a relatively simple apodizing phase plate (APP) that allows improved sensitivity to faint objects at several resolution elements away. These techniques are currently being used to search for extrasolar Jupiter-like planets around nearby stars.
