Multi-directional open path detector system and method of using the same

A receiver for a multi-directional open path detector comprising:

• at least one detector;
• a controller communicably coupled to the at least one detector;
• an optical element;
• and
• a reflector element in reflective communication with the optical element, wherein the reflector element comprises a plurality of reflector faces, wherein each reflector face is configured for being aligned with a transmitter of a plurality of transmitters, and wherein each reflector face is configured to direct the incoming beam from the corresponding transmitter to the at least one detector,
• wherein for each transmitter:
• the reflector element is configured to direct incoming beam from a transmitter towards the optical element;
• the optical element is configured to redirect the incoming beam towards the at least one detector;
• the at least one detector is configured to generate an output signal based at least in part on the incoming beam;
• and the controller is configured to generate a detection signal based at least in part on the output signal, wherein the detection signal is indicative of presence of a detected gas.

A method for detecting gas in a region, the method comprising:

• aligning a receiver with a plurality of transmitters;
• receiving incoming beam, by the receiver, from each transmitter of the plurality of transmitters, wherein the receiver comprises an optical element, at least one detector, and a reflector element in reflective communication with the optical element, wherein the reflector element comprises a plurality of reflector faces, wherein each transmitter of the plurality of transmitters is aligned with a reflector face of the plurality of reflector faces, and wherein each reflector face is configured to direct the incoming beam from the corresponding transmitter to the optical element;
• and
• for each transmitter:
• redirecting the received incoming beam towards the optical element;
• and
• generating a detection signal, by the at least one detector;
• based at least in part on the redirected incoming beam received from the optical element.
