Instrumentation

Lately, I've been developing lower-cost InGaAs detectors for exoplanet transit detection in the near-infrared.  We work with FLIR detectors sensitive over 0.9 to 1.7 microns and are in the midst of building a second-generation camera. We are looking for 0.5-1.5 m telescopes for testing our camera, so please let us know if you would like to work with us!


Inside the housing, a circuit board carries the analog-to-digital signal chain, an Opal-Kelly board hosting an FPGA, and housekeeping electronics. The Opal-Kelly board directly interfaces to a PC using USB.


Here, we are testing the camera in the lab with a microlens array in front to simulate a star field:


This setup produces images like these on the detector from which one can perform aperture photometry:
