  A suite of science instruments is critical to any high contrast imaging
facility, as it defines the science capabilities and observing modes available.
SCExAO uses a modular approach which allows for state-of-the-art visitor
modules to be tested within an observatory environment on an 8-m class
telescope. This allows for rapid prototyping of new and innovative imaging
techniques that otherwise take much longer in traditional instrument design.
With the aim of maturing science modules for an advanced high contrast imager
on an giant segmented mirror telescopes (GSMTs) that will be capable of imaging
terrestrial planets, we offer an overview and status update on the various
science modules currently under test within the SCExAO instrument.
