Image Intensifiers Multiply Photons

Facebook X LinkedIn Email
Applications for intensified CCD cameras range from miniature electronic night vision to low-light imaging of cellular interactions.

Mike Buchin, Stanford Photonics Inc.

Originally developed to enhance night vision in military applications, image intensifiers combined with improved CCD imaging sensors emerged as serious contenders for low-light scientific imaging applications in the early 1990s. Today many intensified CCD cameras employ the same CCD sensor found in cooled scientific cameras, the goal being to combine a high-gain amplifier with a good low-light image sensor. A typical intensifier has three key elements. The first stage is a flat, circular photocathode formed from various semiconductor materials within which photon energy is converted to...Read full article
