Holographic Near Eye Display
PCO team elaborated test methodology of the display, designed in a manner to examine parameters of projected image. Most important parameter to verify is projected image virtual distance as perceived by human observer, as it guarantees the lack of eye accommodation while switching between virtual and real image. For this purpose a distance assessment device utilizing a Raspberry Pi camera
PCO team has created a sample application that allows to display up to 2 selected images (which may be provided in PNG, JPEG or Windows Bitmap formats) using the HANEDA device in real time. The application prepares configuration frames and sends image data for selected images, automatically enabling RLE compression when either of the image dimensions exceeds 1024 pixels. When
One of the scientific goals of the Project was to use the interactive calibration routine for the assessment of the faults of the user’s eyesight. This procedure has been successfully implemented in the project and has allowed for the coarse measurement of the user’s spherical and cylindrical discrepancies from the fine-tuned system (pre-calibrated with high-quality, reference objective lens). The procedure
The laser diodes driver will get a new feature that allows to synchronize with Liquid Crystal state. Liquid Crystal cells in Spatial Light Modulator have a flicker which have a impact on the diffractive efficiency. The new driver will allow to synchronize with a proper LC cell position and state.
The work is still going on. Custom designed binoculars are on the construction. The custom radiators are designed and heat transfer analysis was provided. When all elements will be ready the whole system will be launched with the ability to use it on head.
