Apple ditch the LIDAR and please put in a NIR spectrometer lense in its place.
I believe one of your suppliers has a $5 one the size of a camera lense.
Why? Imagine your iPhone being able to quickly scan objects, and using AI models, predict the content of what you scanned. Need to check your meds? Scan a pill and it'll tell you if it is fake, generic or original and how close to its best before date it is. Brewing beer? Scan your hops and instantly get the current alpha and betas (which degrade over time). Yes, it can scan other herbs and medicines and is already being used in the area some of you may presume. 😉
I could go on and on, the list of applications is huge and expanding rapidly.
It would be the most empowering tool to ever have been added to a smart phone.
