05.17.23 -- High Speed, High Frequency, High Res: A Look At 3 Novel Uses Of Cameras

Operating in a climate-controlled lab or on the Martian surface, back-illuminated sCMOS detectors provide high sensitivity, high dynamic range, and low noise, even in in low-light conditions.

German researcher Dr. Sebastian Voltmer has been looking at the inner planet Venus as a ring next to the sun and how the crescent is getting bigger. According to Dr. Voltmer, the cooled Ninox 640 II SWIR camera provided a much-improved signal-to-noise ratio.

To understand how lenses affect the performance of imaging systems, it is necessary to grasp the physics behind diffraction, lens aperture, focal length, and the wavelength of light. Other design limitations also restrict the optical capabilities of a lens, even before manufac­turing tolerances are considered.

By using the 1.05 µm central wavelength, companies are now developing systems to image deeper through the retina into the blood vessel layer to diagnose eye diseases and monitor treatment.

Deep learning algorithms already support medical imaging in many application areas, such as the classification of mammography examinations, prostate segmentation, segmentation of lesions in the brain, and respiratory tract segmentation.

Digital image correlation, particle image velocimetry, and Schlieren imaging provide engineers in the aerospace industry with insight into the strength and durability of materials, the characteristics of engine combustion processes, the aerodynamics of objects in flight, and much more.

Zygo has been making optics for the NIF’s laser program since the early 1970s, playing a critical role as the NIF’s laser system is the only facility in the world that operates above the laser damage threshold requirements for optics. 

This white paper explains the different approaches, properties, and shortcomings of a photon number resolving camera based on semiconductor technology.
