当前和未来的宇宙微波背景 (CMB) 辐射实验的目标是偏振 B 模式信号。该信号的小幅度使得成功测量对当前技术构成挑战。因此,非常准确的研究来减轻和控制可能的系统效应对于实现成功的观测至关重要。另一个挑战来自极化银河系前景信号的存在,这些信号会污染 CMB 信号。当它们组合在一起时,前景信号在几乎每个相关频率上都支配着偏振 CMB 信号。未来的实验,如 LiteBIRD 星载任务,旨在高精度测量 CMB B 模式信号,以测量 10−3 级别的张量与标量比 r。我们提出了一种方法来研究光度校准要求,以最大限度地减少多频 CMB 实验的 CMB 偏振图中偏振银河前景信号的泄漏。我们将此方法应用于 LiteBIRD 案例,我们发现根据频段,光度校准的精度要求在 ~ 10− 4–2.5× 10− 3 范围内。在探测器不相关的假设下,我们发现每个探测器的要求范围为 ~ 0.18× 10− 2–2.0× 10− 2。最后,我们将校准要求与带通分辨率联系起来,以定义一些代表性带通响应的约束:Δν∼ 0.2–2 GHz。
Current and future Cosmic Microwave Background (CMB) Radiation experiments are targeting the polarized B-mode signal. The small amplitude of this signal makes a successful measurement challenging for current technologies. Therefore, very accurate studies to mitigate and control possible systematic effects are vital to achieve a successful observation. An additional challenge is coming from the presence of polarized Galactic foreground signals that contaminate the CMB signal. When they are combined, the foreground signals dominate the polarized CMB signal at almost every relevant frequency. Future experiments, like the LiteBIRD space-borne mission, aim at measuring the CMB B-mode signal with high accuracy to measure the tensor-to-scalar ratio r at the 10− 3 level. We present a method to study the photometric calibration requirement needed to minimize the leakage of polarized Galactic foreground signals into CMB polarization maps for a multi-frequency CMB experiment. We applied this method to the LiteBIRD case, and we found precision requirements for the photometric calibration in the range∼ 10− 4–2.5× 10− 3 depending on the frequency band. Under the assumption that the detectors are uncorrelated, we found requirements per detector in the range∼ 0.18× 10− 2–2.0× 10− 2. Finally, we relate the calibration requirements to the band-pass resolution to define constraints for a few representative band-pass responses: Δν∼ 0.2–2 GHz.
