摘要

The L/M-band (3−5 μm) InfraRed Camera (LMIRcam) sits at the combined focal plane of the Large BinocularTelescope Interferometer (LBTI), ultimately imaging the coherently combined focus of the LBT’s two 8.4-metermirrors. LMIRcam achieved first light at the LBT in May 2011 using a single AO-enabled 8.4-meter aperture.With the delivery of LBT’s final adaptive secondary mirror in Fall of 2011, dual-aperture AO-corrected interferometricfringes were realized in April 2012. We report on the performance of these configurations and characterizethe noise performance of LMIRcam’s HAWAII-2RG 5.3-μm cutoff array paired with Cornell FORCAST readoutelectronics. In addition, we describe recent science highlights and discuss future improvements to the LMIRcamhardware.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
