Before revision: Infra-red pollution—incident infra-red light is usually filtered on image sensors using a specific thin film dedicated to this task (but which may serve an additional purpose in protecting the relatively-much-more-expensive sensor component from contamination and damage), and so this issue, if truly the result of ir pollution, may be a problem which is independent of the LBCAST technology of the sensor.
