Cone Photoreceptors in the Eye (IMAGE) Optica Caption Researchers used a new imaging technique based on adaptive optics scanning light ophthalmoscopy to acquire images of the smallest cone photoreceptors in the living human eye (left). They also combined their approach with non-confocal split detection (right) to better see the inner segments of the same photoreceptors. The two images are acquired simultaneously and are co-registered with each other.
