We find that the quadrature measurement theory through symmetric beamsplitter can be elaborated more precisely and more directly by virtue of the IWOP technique. Both the normally ordered and anti-normally ordered generating photocurrent operator for mements of photocurrent probability distribution are derived, and their applications are respectively presented.
