The test, published in Scientific Reports 7: 5893, compares the Coherence properties of the following 5 light sources and their effect on the image sharpness and speckle of holographic displays.
EXALOS has expanded its product portfolio with the introduction of a compact RGB SLED module that will enable the advancement of micro-display architectures for augmented reality (AR) and head-up displays (HUDs).
Superluminescent light-emitting diodes (SLEDs) are very attractive as compact, highly efficient light sources for various applications in the visible red spectral region. EXALOS investigated the electro-optical performance of SLEDs operating at center wavelengths of 625-650 nm with interesting results.
Remember the Tamagochi? Here is the next evolutionary step. With AI just around the corner, virtual living animals will become (augmented) reality. And do we need to start thinking about virtual kids?
SLEDs, also known as high-power LEDs and “laser diodes operating below threshold,” are semiconductor light sources that have a broadband output optical spectrum, like LEDs, at high power levels, like laser diodes. This combination is valuable in a variety of applications, and as a consequence, these emitters are finding commercial use.
EXALOS VISIIIBLESRGB are designed as reliable high-performance light sources with a long life span. Stable electrical characteristics during the whole lifetime are one of the most essential features for the acceptance of the emerging new generations of next-to-the-eye display technologies.
Modern Superluminescent LEDs offer distinct optical attributes compared to LEDs and laser diodes and are the preferred choice for imaging applications that call for reduced speckle and minimal interference noise.
The sensitivity of the human eye is rapidly decreasing for the red spectral region with a slightly increasing wavelength. Which wavelength in the red spectral range would be the best for modern lasers and SLEDs.
