Lecture 21: Image Sensors (16)

Do solar panels capture electrons in the same way that sensors capture photons (using silicon)?

Why might a scientific CMOS (sCMOS) sensor be more suitable for certain types of imaging applications compared to a standard smartphone CMOS sensor?

It's cool to see that scientific cameras catch nearly all the light that hits them. This makes them great for taking pictures of stars or tiny cells where you need to see very small details, even when it's pretty dark. They're way better at this than our eyes or the cameras on our phones.

I'm curious if old film cameras quantom efficiency is. Did they work similar to how image sensors work in our iphones and what chemicals were used that achieved the photoelectric effect? Also, how did we interpolate intermediate pixel values in a film color camera?

If human eyes have such low quantum efficiency and smartphone cameras have relatively high quantum efficiency, how come we are so much more effective at night vision? Is this purely due to the computational processing of the brain?

Is it possible to develop a device to achieve a QE of approximately 1? What makes sCMOS so much better than CCDs or phone cameras? Also, does the low QE affect the color gamut of our human eyes?
