    "abstract": "We have demonstrated several inexpensive methods which can be used to measure\nthe deflection angles of prisms with microradian precision. The methods are\nself-referenced, using various reversals to achieve absolute measurements\nwithout the need of a reference prism or any expensive precision components\nother than the prisms under test. These techniques are based on laser\ninterferometry and have been used in our lab to characterize parallel-plate\nbeamsplitters, penta prisms, right angle prisms, and corner cube reflectors\nusing only components typically available in an optics lab.",
