scattered reflection light detection amplifier

I have many years of experience working in photonics and more recently radiation. Sadly I cant show you samples, but I well understand interfacing to both the Si Photo Multipliers (usually Hamamatsu) and Avalanche Photo Diodes. Of course I work in other technologies as well especially for x-ray work. Your document shows a 100MHz pulsed laser. Are you trying to recover the original modulating signal, or just the scattered average? Of course for testing you would need to supply the laser assembly and the pulsed driver.

I used to design optic module with APD detector. I can email a screenshot of my job to you if you interested.

hi, i am an electrical engineer and an embedded system designer. i can help you with this project.

Hi i can help you, you need meter very ultra low current

I can do this,.

done similar work

Let me handle it.

Project Proposal Technical Creation Studios Proposal Submitted To: Freelancer Employer Project ID: 4750023 Project Budget: $750 - $1500 Overall Objective: To provide a one on one interface with the customer, a strong long term work relationship, and provide a quality product that meets the customers’ expectations and required budget needs in the time provided. Project Description: I want the amplifier which can detect the very low scattered reflection light on plain color paper from the focused pulse laser.
