If you're gonna share clickbait titles, you could at least add a short summary like this:
the Bayer filter—a red, green, and blue layer that sits above the sensor and adds color to your images—absorbs and wastes around 60 percent of that light before it can reach the sensor. To make a red pixel, the filter blocks and throws away blue and green light.
Now, the Boston company Metalenz has acquired an Israeli startup called PxE Holographic Imaging, which has developed a new optical layer called a HoloCoder. This microscopic structure sits directly on top of the image sensor and diffracts light, bending the light waves rather than absorbing them.
