Claim 5:
6. The discrete light detection device as claimed in claim 1, wherein the light intensity sensors of the discrete light detection unit comprise at least one peak light intensity sensor and at least one trough light intensity sensor;
wherein the discrete optical filters of the discrete light detection unit comprise at least one peak intensity optical filter and at least one trough intensity optical filter;
wherein the at least one peak intensity optical filter is mounted corresponding to the at least one peak light intensity sensor, and the at least one trough intensity optical filter is mounted corresponding to the at least one trough light intensity sensor;
wherein the light intensity signals generated by the discrete light detection unit comprise at least one peak light intensity signal and at least one trough light intensity signal;
wherein the at least one peak light intensity sensor generates the at least one peak light intensity signal according to the collimated beam filtered by the at least one peak intensity optical filter;
wherein the at least one trough light intensity sensor generates the at least one trough light intensity signal according to the collimated beam filtered by the at least one trough intensity optical filter;
wherein when the processing unit receives the at least one peak light intensity signal and the at least one trough light intensity signal, the processing unit determines whether a difference of the at least one peak light intensity signal minus the at least one trough light intensity signal is greater than or equal to a configured intensity threshold; and
wherein when the difference is greater than or equal to the configured intensity threshold, the processing unit generates the detection result as an alert signal; and vice versa, the processing unit generates the detection result as a safe signal.
