The Planetary Systems Imager for TMT: overview and status

We will provide a summary review of the capabilities and the overall status of the Planetary Systems Instrument (PSI), a second-generation instrumentation suite for the TMT. The PSI concept follows a modular design and operates from optical to thermal infrared wavelengths, combining high-order AO correction with coronagraphs, imaging and low-resolution integral-field spectroscopy, and fiber-coupled spectrometers. We will provide an overview of recent development, including description of the key requirements, performance simulation, optical front-end AO design concept, and precursor instrumentation and technique status.
