Abstract

The tomographic properties of integral-code (multiplexed) measurement systems with multiple-pinhole hexagonal coding collimators are investigated. It is established that systems with collimators designed on the basis of nonextended classical pseudorandom sequences possess the best point spread functions (PSF). Point spread functions based on extended sequences formed from one and the same classical pseudorandom sequence possess similar properties.
