Title: Non-contact id tag system and data reception method in interrogator therefor
Inventor: MIURA YUZO
IPC: G06K19/07
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To improve response data detection sensitivity in a non-contact ID tag system and to enlarge the operatable area of a non-contact ID tag. SOLUTION: In a response data reception period, switches 21 and 23 are turned OFF and response data outputted from filters 9 and 12 are inputted to reception amplifiers 10 and 13 as they are and amplified. In the other period, the switches 21 and 23 are turned ON and input to the reception amplifiers 10 and 13 is attenuated. Thus, since large amplitude change outputted from the filters 9 and 12 is suppressed at the time of interrogation data transmission, even when the characteristics of the reception amplifiers 10 and 13 are set so as to sufficiently amplify the response data with less amplitude change, the saturation of the amplifier by interrogation data is prevented and the detection sensitivity of the response data is improved.

Abstract: PURPOSE:To enable change of polarization characteristics without losing a quantity of light by spliting a luminous flux to two luminous fluxes having different polarization components, then polarizing one of the luminous fluxes to the luminous flux having the same polarization characteristic as the polarization characteristic of the other luminous flux by a polarizing means and combining again both the luminous fluxes to one luminous flux. CONSTITUTION:The luminous flux which is radiated from a light source 10 and has random polarization characteristics is entered at an arbitrary luminous flux width to a polarized beam splitter 18 by the effect of two lenses; a diffusion lens 12 and a condenser lens 14. The incident luminous flux is then split to P polarized light and S polarized light in the polarized beam splitter 18. One of the split luminous fluxes transmits a halfwave plate 20 and is made into the luminous flux having the same polarization characteristic as the polarization characteristic possessed by another luminous flux. Both the luminous fluxes are then entered to a hexagonal prism 22 by which the fluxes are combined to one luminous flux. This luminous flux is outputted through a lens 24 and a lens 26. The distribution state of the quantity of the resulted luminous flux is, therefore a combination of the two distributions of 1/2 the quantity of light. The change of the polarization characteristics without losing the quantity of light is thereby enabled.
