Description
I will present a review of LiteBIRD systematics. LiteBIRD aims for measuring the tensor-to-scalar ratio, r, with an accuracy less than 0.001. Given the current sensitivity of the observation devices, the systematic effects yield the dominant contribution in the error of r. I will present an overview of the possible systematic sources, and the procedure to evaluate the effects and to give requirements. I also discuss possible mitigation of the systematic effects with the optimization of the scan strategy and the usage of the polarization modulation.
