Abstract
Systems and methods for detecting target chemicals are disclosed. A system includes a chemical sensor configured to filter light. The chemical sensor includes a referencing arm configured to output light at a first intensity level and a sensing arm sensitive to a target chemical. The sensing arm is configured to output light at a second intensity level. A difference between the first intensity level and the second intensity level indicates a presence of the target chemical.
