Technically, the glass is always full
Optical engineering is a field of study which focuses on optical techniques in engineering and system design applications. The primary focus on Optical designing is to create parts like lenses and another medium that make use of properties of light. Creating a smart device using optical application which transfers the power of light into something unique, useful and wonderful is harder than conquering the Everest. A process this difficult takes hard work, dedication and a strong, powerful mind of optical designers work in a precise manner to achieve a perfect result.
Over these years Optical designing played a remarkable role in the study of distant planets and numerous other phenomenon using their cutting-edge ultra-precision instrument. Inventions in the field of optical design show remarkable increase year after year. Besides researching these wonders, we get so excited to work with optical components which is now a part of our daily routine. The amazing technique of Optical applications used from polarized sunglasses to the car’s windshield is the proof that the potential of the use of light rays are endless and will revolutionize our life for better.
Heads up Display (HUD)
Before we began implementing the design, a full-fledged researched and development (R&D) process was carried out; there wasn’t one thing that wasn’t researched and studied. From available similar devices in the market to understanding the bounding box size within which the optics were to be applied. We came across TFT based large HUD module which could not solve the problem of the aftermarket device.
We realized that the DLP technology would be the best go ahead with. To make sure there are no product inconsistencies, and to ensure optimum utilization in the least possible time, we used the best software available in the market for the optical design.
Refractive V.S Reflective Optics
Our decision to work with the reflective optics was a simple yet genius one, as we could do it with lesser number of components and further, it reduced the chances of chromatic (color) aberration to almost negligible. We had to work with the various connected parameters of HUD from the Eye-Box, Field of View to the resolution and distance of the virtual image.
It required from us some simulation iterations that had to be done, and we later had to write a code to explicitly control the application and perform the numerous iterations. Apart from the fabrication of combiner, coating of the surfaces was another complicated task for us which we succeeded in.
Optical coatings are used for various purposes: to alter the reflectance, transmittance, and absorbance, or to polarize properties of optical components and to be honest, it’s quite hard to achieve. This challenging development will be evident from the below process: The coating is deposited in the high vacuum using the process of evaporation in conjunction with a source. The patented optical design for Exploride HUD is done keeping the focus on the best visual experience that can be provided to the user.
Finally, after 9 months of hard work and gulping down countless cups of coffee, we have the optical engineering all ready to be put out on the market. We are focused on providing an amazing driving experience and connectivity on the go in a safer way, which we are very sure about.
