Abstract

The L/M-band Infrared Camera (LMIRcam) is a first-generation imager being constructed for the Large Binocular Telescope Interferometer, operating at 3-5 μm. Given the high sky background at these wavelengths, an FPGA-based controller provides high-speed, flexible data acquisition. Originally designed for FORCAST, a mid- IR camera/spectrograph built by Cornell University, the controller was modified to interface with LMIRcam's Teledyne HAWAII-1RG 1024×1024 array. In order to facilitate the different operating modes and increased array size, we have developed a modified version of the FORCAST device driver, reconfigured the FPGAs, altered the control software, and plan to implement a window mode.
