Hello everyone, hope you are doing great, I am directing two laser beams, each with a power of 1.32mW, into the human eye simultaneously. One beam converges at the cornea with a spot size of 40um, while the other remains collimated at the cornea and converges at the retina with a spot size of 30 um. My query is whether it is feasible to track the reflected beam power at various segments of the eye, such as the cornea, lens, and retina. I would appreciate guidance on designing such a system.

Thank you in advance for your assistance.
