Systems and methods are described for spatial-heterodyne interferometry for transmission (SHIFT) measurements. An apparatus, includes: a source of coherent light energy; a reference beam subassembly optically coupled to the source of coherent light; an object beam subassembly optically coupled to the source of coherent light; a beamsplitter optically coupled to both the reference beam subassembly and the object beam subassembly; and a pixilated detection device optically coupled to the beamsplitter. The object beam subassembly includes an object that is at least partially translucent, the object transmissively optically coupled between the source of coherent light energy and the beamsplitter.
