We demonstrated the Talbot effect using a broadband hard x-ray beam (Δλ/λ ~1). The exit wave-field of the x-ray beam passing through a grating with a sub micro-meter scale period was successfully replicated and recorded at effective Talbot distance, Z(T). The period was reduced to half at Z(T)/4 and 3/4Z(T), and the phase reversal was observed at Z(T)/2. The propagating wave-field recorded on photoresists was consistent with a simulated result.
