Hi everyone,
I currently working on a project called laser based distance measurement beyond 50m. I'm using laser as source and BPW34 as a receiver to implement TOF measurement. The problem is depending on light intensity, photodiode response is changing i.e. Time value is perfect when photodiode gets hit by laser directly but time changes when when a part of light gets hit on the photodiode. So, I guess depending on the intensity of light rising edge time is changing. Any suggestions ?? I am currently using transistor to get digital logic in receiver. Any modifications to be done in circuit ??
