We present a progress status of a new concept of PID detector called FDIRC, intended to be used at the SuperB experiment, which requires pi/K separation up to a few GeV/c. The new photon camera is made of the solid fused-silica optics with a volume 25-times smaller and speed increased by a factor of ten compared to the BaBar DIRC, and therefore will be much less sensitive to electromagnetic and neutron background.
