Cascaded Detectors to Increase Detection Rates
Efficiency of the NIR system can be improved by sequentially cascading separate NIR detectors and using the combined results of both to produce a single measurement.
Introducing the appropriate number of sequential detectors for a specific application produces minimum requirement of 95% detection rates.
If properly configured, overall false positive rates are typically around 3%.
