Abstract
A method of calibrating an optical detector includes installing a calibration system within at least one sensing volume of the optical detector, filling a chamber of the calibration system with a material to achieve a known obscuration, and measuring an obscuration of the material within the chamber.
Claims14
A calibration system for use with a detector comprising:
- a housing having an internal chamber;
- at least one reservoir arranged in fluid communication with the internal chamber;
- and
- a controller for selectively supplying a flow of material from the at least one reservoir to the internal chamber such that the internal chamber has a known obscuration.
