Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 19:
20. The optical device of claim 18, wherein the processor executes the instructions to determine a confidence value based on the signal count and the ambient count using the equation, C
   =
   
    
     S
     -
     
      W
      ·
      
       S
      
     
    
    A
   
  
  ,
 

wherein C is the confidence value, S is the signal count, A is the ambient count, and W is a number between 0 and 1, inclusive, wherein gating the output of the SPAD cluster comprises gating the output of the SPAD cluster in response to the confidence value being lower than a confidence threshold.
