Spectroradiometer With Specialized Lens for Characterizing Head Mounted Displays

Active

Contract Opportunity

Notice of Combined Synopsis/Solicitation. This is a combined synopsis/solicitation for commercial products or commercial services prepared in accordance with part 12. This announcement constitutes the only solicitation; quotes are being requested, and a separate written solicitation will not be issued.

Background:

The procurement is to support regulatory science tools development for the Interventional, Radiological Imaging and Visualization program. Developing measurement methodologies for technical performance is critical for consistent evaluation of image visualization on head mounted displays. Specifically, the procurement is for a spectroradiometer to precisely measure and evaluate the spectrum and color performance of image quality of augmented and virtual reality head mounted displays that are increasingly being incorporated in medical devices across the Office of Product Evaluation and Quality (OPEQ). The quantitative measurements from the spectroradiometer will allow for developing image quality regulatory science tools for a wider range image quality parameters across the full range of device types, opposed to only measuring luminance values. The specialized lens assembly on the spectroradiometer mimics the human visual system, which is critical for determining the image quality seen by the user. This will align the Office of Science and Engineering Laboratories (OSEL) instrumentation with FDA recognized standards, such as the International Electrotechnical Commission (IEC), for head mounted displays, which is essential for the OSEL mission of developing regulatory science tools.
