THE CHALLENGE
Conform thin CMOS image sensors to a controlled curved surface without fracture or loss of electrical function, enabling simpler high-performance optical systems.
Conform thin CMOS image sensors to a controlled curved surface without fracture or loss of electrical function, enabling simpler high-performance optical systems.
MY CONTRIBUTION
I developed precision fixtures and processes for bending, positioning, and bonding the sensors to curved molds. I designed machined tooling, controlled the loading and alignment approach, and used Keyence confocal metrology to generate high-density surface maps for shape verification and process refinement.

OUTCOME
The team produced three functional curved sensors that were demonstrated in a working f/1.2 camera, validating both the mechanical process and the optical concept.
