Although smoke detectors are actively being studied to reduce false fire alarms, they still face challenging issues such as complex and elaborate alignment, high cost, large size, and poor performance ...

To address the problem of short-range laser circumferential detection, this paper proposes a static detection method based on a transmissive-reflective combined optical system, Building upon previous ...
