Dr. Ðenan Konjhodžić

Ort: Online

Nowadays, the pandemic situation caused by the COVID-19 virus inspired many companies, research institutes and lighting designers to adopt UV radiation as a new tool in their projects and research. The promising germicidal effect of the UVC radiation also on the Coronavirus raises the question of the reliable measurement of the UV radiation. However, this complex task needs an expertise and appropriate equipment.

Quality control of AR/VR near-eye-displays: Goniometric versus advanced 2D imaging light measurements

Datum: 28.03.2021 – 30.03.2021

Dr. Tobias Steinel

Ort: SPIE AR/VR/MR, San Francisco

Novel display technologies for AR/VR/MR devices require advanced imaging systems to control quality during assembly and to calibrate the device. Such calibration yields an optimal match of left and right eye and allows color management for an accurate match of real world and virtual objects. For accurate measurement, such an imaging system should be based on a lens system that mimics the human eye system and have a similar-sized entrance pupil in front of the lens. Traditionally two approaches have been proposed:

Dr. Tobias Steinel

Ort: electronic displays Conference 2021 Digital

Novel display technologies for augmented and virtual reality (AR/VR/MR/XR) devices, like Head-Mounted-Devices and Head-Up-Displays, require advanced imaging systems and calibration to control quality during assembly to accurately match the real world and virtual objects. We demonstrate and compare advantages of goniometric sampling spot measurements and camera based imaging solutions.

Characterization of VCSELs for 3D sensing applications according to the IEC60825-1 Standard

Datum: 19.01.2021, 07:00 (EST)

Dr. Katharina Predehl

Ort: Online Event

VCSELs have special properties in contrast to other typical laser sources. As a result, VCSEL eye safety evaluation is more complex and a couple of additional aspects have to be considered that would not apply for "normal" lasers. Consequently, the validation of a VCSEL's laser class is not trivial, and even more so because an easily understandable guideline for the assessment of VCSEL safety has not yet been published.
