Though not as low-cost.
> Multispectral imaging (oh and faster OCT) in a portable unit would be clinically useful
Wave field cameras capture phase per pixel. That's probably medically usual.
I have been researching convergent holographic medical imaging and treatment using Continuous Wave (CW) laser with longitudinally-polarized beams, possibly at 1 Watt per laser plus the cost to run the active mask and the (Amplituhedron-applied) holographic transform on a DGX for sub-wavelength scale holography.
From working on optical tweezers, I learned that CP-L + CP-R cancels the transverse and leaves a sort of blurry but narrow focal spot of longitudinal wave, and that CP + HP, and HP-L + HP-R have an even more precise focal spot. (CP: Circularly Polarized, HP: Helically-polarized, L/R: Left/Right).
OpenLIFU (low-frequency ultrasound array) is much further developed as a medical imaging and treatment capability.
Things that can be diagnosed from fundoscopy FWIU: MedicalSignOrSymptom(s), ocular disorders, Diabetes, ASD, Schizophrenia, general psychosis,
How to balance privacy of PHI against the advantage of early low-cost diagnosis?
For most ophthalmologic practices, storing fundoscopy in the chart (EHR) to track conditions over time would be an improvement.
