Simple 1-axis scanning laser lidar system

How do you recieve the laser light?

@1dieu a single CdS photoresistor is embedded within a tubular light shield (i.e. pen cap) next to the laser diode. i don't have the means to accomplished phase-based detection, so it's all amplitude-based. i've since discovered numerous advantages to ultrasonic sonar over optical proximity detection, so that's what i've been focusing on lately. cheers! -- Peter

Thanks

I'm now in to this

so everthing is new voor me.
