    Hi,

    If my guess is correct you may be trying to build a Infrared touch screen based application. google about Infrared touch screen and allignment of IR Led's is the trick there i don't find any other

    to get 30 cm range u must use high power and directive IR LED and use TSOP IR sensor at receiver side

    for removing interference use TDM technique. means at a time only one IR LED and sensor are active. all other are deactive.
