  - Altermagnets are a class of collinear magnets that exhibit non-relativistic spin
    splitting (NRSS) of electronic bands in the absence of net magnetization. Their
    potential to generate large spin polarization without spin-orbit coupling has
    created strong interest in probes that access the underlying order parameter directly.
    In this Perspective, we show that linear magneto-birefringence (LMB) provides
    a natural and broadly applicable route to detecting altermagnetic order. Building
    on the correspondence between the momentum-space structure of NRSS and the ferroic
    ordering of magnetic multipoles in real space, we demonstrate how $d$-wave and
    $g$-wave NRSS textures yield distinct LMB responses. We present a symmetry-based
    framework that identifies the optical geometries and field configurations required
    to isolate specific multipole components, enabling domain imaging and providing
    benchmarks for theoretical models of LMB.@eng
