Continuous phase spaces have become a powerful tool for describing, analyzing, and tomographically reconstructing 

quantum states in quantum optics and beyond. A plethora of these phase-space techniques are known, however a thorough 

understanding of their relations was still lacking for finite-dimensional quantum states. We present a unified approach to 

continuous phase-space representations which highlights their relations and tomography. The quantum-optics case is 

then recovered in the large-spin limit. Our results will guide practitioners to design robust innovative tomography schemes.
