SWIR Colloidal Quantum Dot Sensor Bandwidth and Thermal Stability: Progress and Outlook
Tue, Sep 20, 2022 1:00 PM - 2:00 PM EDT
Ethan Klem, Ph.D. of SWIR Vision Systems provides an overview of the performance of high-definition colloidal quantum dot (CQD) sensors and shows the less than 3 nanoseconds rise and fall time found by testing the response time of the photodiode structure using a pulsed laser source. He also presents data that demonstrates stable device operation at elevated temperature and humidity conditions. Shortwave infrared (SWIR) sensors, made using CQD photodiodes, offer CMOS-like opportunities for highly scalable, small pixel pitch sensors. This is due to the sensors’ straightforward, monolithic integration with silicon circuitry.
Spectral Domain Optical Coherence Tomography Spectrometers for Today and Beyond
Wed, Sep 21, 2022 1:00 PM - 2:00 PM EDT
Spectral domain optical coherence tomography (SD-OCT) is commonly used for ophthalmologic applications, particularly in the diagnosis and treatment of macular degeneration. It is also consistently used in research for new applications in both medical and manufacturing sectors. Heidi Olson of Ibsen Photonics discusses some of the methods currently available to achieve better SD-OCT images, as well as the new applications that can be unlocked with further development. The limitations of the available products are also explored specifically in reference to how the boundaries can be pushed to achieve better quality data with relaxed performance requirements.
