A collimator for a detector is disclosed. The collimator comprises: a bottom plate provided with imaging through holes distributed in an array, each of the imaging through holes comprising a first hole segment and a second hole segment, the transverse size of the first hole segment gradually decreasing in a direction from a free end to the second hole segment, and the transverse size of the second hole segment gradually decreasing in a direction from the free end to the first hole segment; a shielding case formed on the bottom plate; and a top plate disposed in the shielding case and closing at least a part of an opening of the shielding case, the top plate being provided with shielding through holes distributed in an array, and the imaging through holes being in one-to-one correspondence with the shielding through holes.

Collimator for detector and application thereof

A gaming system, computer-implemented method and gaming device are operable to determine player identification data corresponding to a player in a property corresponding to a selected one of multiple gaming operator nodes, compare the player identification data with each of multiple data blocks in a block chain to determine a match between the player identification data and one of the data blocks, and responsive determining that the player identification data matches one of the data blocks, send an alarm signal to a gaming operator that corresponds to the selected one of the gaming operator nodes.
