“…To date, no other wearable devices have achieved these three features whether the devices are using VRDs [9][10][11][12] or conventional liquid color displays [18][19][20][21]. These characteristics will enable RETISSA ® to be used in a variety of application segments from low-vision aids, workplace support, retinal testing medical equipment, entertainment to the consumer-oriented smart glass.…”

“…Microvision Inc., founded in 1993 based on the technology spun off from the HIT Lab, built a prototype called Nomad Personal Display System with the targeted applications in workplaces [9]. Brother Inc. demonstrated its eyewear named AiRScouter in Brother World JAPAN 2010 [10][11][12]. However, both companies never reached commercial production and ceased development in the end, probably because their prototypes with large optics in front of the wearer's face did not appeal to any customers in any field.…”

Retinal Imaging Laser Eyewear has a miniature laser projector inside the frame which provides the wearer with digital image information through the pupil using the retina as a screen. This compact universal-design eyewear features focus-free and augmented-reality image independent of the wearers' visual acuity and point of focus. This paper describes the background of this technology, the principle of focus-free imaging, the device with a trademark of RETISSA ® , and its laser safety analyses based on international guidelines and standards.

“…Therefore, the color signal can be obtained every 162 ns. For instance, if the system is used for a retinal scanning display (RSD) 19) with 50 frames/s, color signals with 120,000 pixels/frame (400 Â 300) can be generated. The proposed modulation system was constructed in practice as follows.…”

An acoustooptic modulator (AOM) driven by a surface acoustic wave (SAW), in which laser light of the three primary colors, red, green, and blue (RGB), can be modulated by the same modulator at the same driving frequency, was investigated. To suppress the light power leaked to the outside of the waveguide, a waveguide-type AOM with a 3.5-mm-deep waveguide was fabricated. The RGB laser lights were modulated with the diffraction efficiencies of 73 -85% and a driving SAW power of less than 0.2 W at the same driving frequency of 245.5 MHz. By combining the AOM module, laser sources, WDM couplers, and fiber delay lines, a simple simultaneous modulation for RGB laser lights was proposed and constructed. On the basis of the designed properties, the switching time of the output signal from the constructed system equipped with the AOM with the three-finger-pair interdigital transducer (IDT) was demonstrated to be 28 ns. #
