N2 - We have studied the effect of beam collimation on the quality of images obtained with Talbot-Lau interferometry at the RADEN beam line in the J-PARC Materials and Life Science Experimental Facility. By using four typical beam collimations of RADEN, which were determined at a position relatively far from the interferometer, the blurring of images and the average intensity and visibility of interference patterns were observed. From these data, spatial resolutions and measurement precisions of images were experimentally evaluated. The obtained characteristics on each collimation condition are useful to design and optimize a new interferometer, and perform experiments at this beam line.
