  • Live Vesicle Trafficking

    The St Johnston Lab is primarily interested in how cells become asymmetric so that they can perform distinct functions on opposite sides of the cell. This is known as cell polarity.

  • Measuring the Position of Galactic Objects

    While the cutting-edge performance in astronomical observations is achieved by space based telescopes and ultra large telescope facilities on earth, researchers use and develop new smaller measurement facilities for specific measurement tasks and other applications that do not require the immense resources of larger facilities.

  • InGaAs Cameras: The Basics

    InGaAs sensors are used for applications in physical and life science that require high sensitivity over the 900-1700 nm wavelength range, referred to as shortwave infrared (SWIR). Some InGaAs sensors are able to measure up to 2500 nm due to changes in material composition.

  • Advanced Back-Illuminated CMOS Provides an Alternative to EMCCDs for Dynamic, Faint Astronomy

    Ground-based optical astronomy investigates various objects in space, from galaxies to exoplanets, via visible light. Some of these objects are dynamic and move at high speed through the sky.

  • Sensor Improvements to Enhance UV Sensitivity from 10 – 400 nm

    Ultraviolet light spans over the wavelength range of 10-400 nm. It is used for many different applications, from material analysis to plasma diagnostics, with different sections of the wavelength range providing different application solutions.

  • Silicon-based CCDs: The basics

    A CCD is an imaging device that detects photons, converts them into photoelectrons and moves electrical charge. They are comprised of a silicon surface onto which an integrated circuit is etched.

  • Deep Penetration In Vivo Imaging in NIR-II

    Prof. Fan Zhang’s research group, from Fudan University, is centred around in vivo­ fluorescence and biomedical imaging that cannot be detected using traditional fluorophores emitting over the visible wavelength range. His team focuses on creating and characterizing fluorescent probes to detect human disease, as well as imaging approaches to optimize fluorescent probe detection.

  • Automating Acquisition with MATLAB® as Camera Temperature Changes

    Before certain experiments, it is useful to take a series of measurements while key acquisition parameters change. The resultant data can then be utilized to optimize acquisition conditions.

  • Teledyne e2v launches new OctoPlus line scan cameras for Optical Coherence Tomography

    Teledyne e2v, the global innovator of imaging solutions, has developed a new range of line scan cameras for Optical Coherence Tomography (OCT) applications in healthcare and industrial markets.

  • Introduction to X-ray Diffraction

    X—ray diffraction is a non-destructive technique that utilizes elastic scattering to determine atomic structural information about crystalline samples. It requires high energy hard x-rays, as they have an extremely small wavelength, to discern details on the atomic level.

  • eXcelon® Technology – Novel, Performance Enhancing CCD Technology

    Since their invention in 1969, charge-coupled devices (CCDs) have been used to detect the faint light from items as nearby as cells under a microscope to those as far away as stellar objects at the edge of the known universe.

  • Full Well Capacity and Pixel Saturation

    Full well capacity is defined as the amount of charge that can be stored within an individual pixel without the pixel becoming saturated. It is dependent on the pixel size of the sensor and the camera operating voltages.
