Space claim ansys5/21/2023 The two products are designed to interoperate for this purpose with efficiency and ease. You then design methods for remediating the stray light's influence, typically by reconfiguring the lenses in the camera or swapping in new materials that have different optical properties.Īnsys Speos and Ansys Zemax OpticStudio include powerful capabilities for performing stray light analysis to help reduce or eliminate stray light at an optical system's sensor. To solve this problem, you seek ways to identify extraneous critical light source positions, which can be inside or outside the camera’s field of view. Stray light is the unwanted scattered or spectral light that also arrives at the sensor, which compromises the image quality of optical designs by distorting and washing out the image - effectively reducing the sensor's overall dynamic range. ![]() You design optical systems for the desired path you want light to follow through the optics en route to a sensor. What is Stray Light and how do you fix it? With the ongoing market imperatives to make smartphone cameras smaller and more lightweight, optical teams need tools and protocols that will help them identify and remediate stray light in their designs to preserve superior image quality. Because the cameras can be used in virtually any environment, their design must account for stray light in a variety of existing lighting conditions, such as dimly lit rooms, outdoor playgrounds on a sunny day, and busy nighttime roadways full of streetlights, moving vehicles' headlamps, and lighted signs. In the case of smartphone cameras, stray light is a common culprit for blurring and discoloring images. Stray light can lead to unwanted bright spots, which reduces image contrast and a system’s dynamic range. ![]() This image quality is measured by resolution and contrast. More than ever, a primary challenge in the design of many optical products is achieving the clearest possible image, whether it's for a space-based telescope, a nanoscale camera, or the head-up display (HUD) in a car.
