    In order to investigate morphology of spindle-type hematite (α-Fe2O3) particles, electron holograms were observed with imaging plates using a transmission electron microscope (TEM) equipped with a field emission gun and a biprism. Crystal thickness estimated by the shift of interference fringes agrees well with the value expected from the shape of the particle. Furthermore, local fluctuation of the interference fringes due to the particle morphology indicates the fluctuation of about 18 nm. These results clearly demonstrate that observation of holograms with new recording systems such as imaging plates is promising to characterize the detailed morphology of small particles.
