Active laser cavity particle counters: a fundamental problem and solution for airborne application.
A previously unreported air-density-related detuning effect for active cavity aerosol optical particle counters is described, and a simple device for correcting the problem is presented. Airborne field tests with and without the correction device illustrate the effect and the good degree to which the deficiency can be overcome. The effect is shown to have an important impact on instrument calibration.
