摘要：

The design for a fast absorption tomography instrument is presented. The instrument is capable of generating 100 projections of 100 elements each in less than 200 ns. It comprises temporally multiplexed fiber-optic fan-bean sources and large-area fast photodiodes. The spectral operating range is 200 to 1100 nm when silicon photodiodes are used. The sensitivity of the instrument is limited by laser speckle noise created by the fiber optic. The performance was evaluated by using a prototype system.
