我们描述了一种频域多路偏置解调系统的信号处理逻辑、固件和软件，该系统用于读出毫米波宇宙学望远镜的跃迁边缘传感器测辐射热计阵列。该系统依靠现场可编程门阵列进行控制、计算和信号处理，用更小、更省电的系统取代了混合信号读出后端。新系统足够强大、自动化和高能效，可以在平流层气球载望远镜上飞行，并正在进一步开发用于卫星应用。
We describe the signal processing logic, firmware, and software for a frequency-domain multiplexed biasing and demodulation system that reads out transition-edge-sensor bolometer arrays for millimeter-wavelength cosmology telescopes. This system replaces a mixed-signal readout back end with a much smaller and more power-efficient system relying on field-programmable gate arrays for control, computation, and signal processing. The new system is sufficiently robust, automated, and power efficient to be flown on stratospheric balloon-borne telescopes and is being developed further for satellite applications.
