We present a beam combining technique capable of direct instantaneous imaging. The particularity is that the image (or PSID, point source intensity distribution) is formed in a pupil plane. We present the concept on a theoretical basis, comment on the PSID for on- and off-axis sources and finally compare it to Fizeau imaging. Future experiments and reflections about this concept are finally considered.
