We demonstrate an optical method to engineer optical Schrodinger cat states (SCSs) of large amplitude in the range from 2 to 3 with high fidelity close to 0.99. The approach uses the {\alpha}-representation of the SCSs in infinite Hilbert with base displaced number states characterized by the displacement amplitude {\alpha}. An arbitrary {\alpha}-representation of SCSs enables to manipulate the amplitudes in wider range of parameters that which greatly expands the possibilities for generation of the states. We consider a general optical scheme for implementation of the conditioned states close to SCSs with linear optics methods and detectors projecting unitarily transformed initial state onto target. Different input states (number and coherent states, Schrodinger kitten states) are selected as input.
