In search of cost effective sensor to determine depth

Great question! Yes, characterization is a part of my project. In specific the title is recognition/characterization of surface defects. I'll edit my post to include it.

I have a meeting this Friday where I will be asking if they specifically want me to return how deep a scratch/defect is, or if solely identifying a defect and categorizing it is sufficient.

Sorry for the long response, but I found this research paper last night. Basically outlines an open source system for laser triangulation that achieves ~200µm depth estimation. The hardware comes out to ~$600, but they unfortunately did not post their code. I am comfortable with my programming skills. Do you think this is doable? https://www.researchgate.net/publication/369039705_Low-Cost_Automation_An_Open_Source_Laser-Triangulation_Sensor_based_on_ROS_2

Thank you for the response!! If you don't have time don't worry about the research paper I sent, just looks like my best option currently but I'm not knowledgeable enough to know whether to commit to it or not
