Tech Tip Tuesdays with Ansys Optics: Parking Assistance Camera Integration Park assist cameras are critical for enhancing vehicle safety, aiding drivers with precise parking maneuvers by providing clear visibility and a comprehensive field of view. Evaluating camera performance across various vehicle conditions is essential to ensure these systems function reliably. In this article, we present a straightforward workflow for integrating park assist cameras, allowing us to proactively address potential issues and refine the specifications of both the optics and the sensor. We use Ansys Zemax OpticStudio to design and export the optical system, then leverage Ansys Speos to position the camera and ensure it meets parking regulation standards such as FMVSS 111. Finally, we’ll generate the final sensor image using the Speos Sensor System Exporter. Here are the steps: Step 1: Lens system design export with Ansys Zemax OpticStudio Transfer a Reduced Order Model from Ansys Zemax OpticStudio to Ansys Speos. Step 2: Lens system integration with Ansys Speos Assess the camera performance on the vehicle. Step 3: Sensor image generation using Speos Sensor System Exporter Generate a camera image or movie file from a simulation result.

Ansys Optics Fundamental Fridays - Silicon Photonics Silicon photonics (#SiPh) is a platform for constructing photonic integrated circuits (PIC) for optical communication, high-speed data transfer, and photonic sensing devices. The semiconductor substrate material is a silicon-on-insulator (SOI) wafer. Standard #semiconductor manufacturing processes are used to create components on a #photonic layer from silicon (Si), which is transparent to infrared light. Silicon dioxide (SiO2) or air is placed around the silicon to create a high refractive index difference, causing the light traveling in the components to travel through the circuit with very little loss. On-chip photonic integrated circuits are very compact, use less power, and operate at higher speeds (over 100 Gb/s) than traditional photonics devices, transferring information faster and more efficiently than electrical circuits. Advantages of Silicon Photonics Using light to carry information has significant advantages over electrons, radio waves, or microwaves. Light's higher frequency and its multiple modalities (frequency, amplitude, phase, etc.) allow for transmitting more information with low power consumption. These advantages are multiplied when the photonic devices are built into the same chip as the electronics needed for their operation, enabling the use of low-cost mass-production manufacturing processes. Because the technology combines optical components with the electrical circuits on the same chip, optoelectronic devices can be packaged into a smaller form factor than separate optical and electrical solutions. Because light travels through the waveguides with very little loss and because of their microscopic size, silicon photonic devices consume less energy than electrical or stand-alone optical devices. However, the most significant advantage of silicon photonics is its use of existing #CMOS manufacturing systems. Semiconductor manufacturers worldwide create more than one trillion chips of various kinds a year. Companies leverage the tools used to design, manufacture, package, and test semiconductor hardware for silicon photonics technology. Many semiconductor foundries are establishing standards for photonic integration designs, enabling faster, less expensive, and more robust new product development. Applications The most common use is in high-speed data transfer over fiber optics. Companies are focusing on improving the capabilities of optical transceiver chips to make them available for a wider range of applications. Some emerging applications that are leveraging SiPh technology for photonic components include: ▪️ Photonic sensors ▪️ #Lidar ▪️ Quantum computing and networking Read the full article to learn more: https://ansys.me/3AsOk3Q #SiliconPhotonics #QuantumComputing

Tech Tip Tuesdays with Ansys Optics: Fraunhofer (FFT) MTF Modulation Transfer Function (MTF) is a crucial method for capturing the performance aspects of an optical system, essentially a lens or lens assembly. MTF describes the transfer of modulation from the object to the image as a function of spatial frequency, which refers to the recurring distributions of light and dark (contrast) at a particular resolution in images. It combines resolution and contrast into one specification, making it a vital tool for specifying lens performance and as an optimization and tolerancing target during lens design. Ansys OpticStudio can compute the MTF for all target types with high accuracy. OpticStudio offers various sampling schemes and algorithms to measure MTF in your optical applications: MTF, Fraunhofer (FFT) MTF, Geometric MTF, and Huygens MTF. This blog focuses on the Fraunhofer (FFT) MTF, which has recently seen productivity enhancements. OpticStudio’s MTF analysis feature, which can produce a graph of MTF for all spatial frequencies that the lens can support, uses an algorithm based on the Fraunhofer diffraction theory. This well-known method involves a fast Fourier transform (FFT) of grid rays traced to the pupil. The resulting MTF is the modulation as the function of spatial frequency for a sine wave object, based on specific assumptions around the size of f/# or ratio of the focal length, the size of the region over which diffraction PSF has significant energy, the distortion of the exit pupil, and the sampling setting. Not all optical imaging systems meet the simplifying assumptions for the Fraunhofer diffraction theory used by the FFT MTF algorithm. However, only specific spatial frequencies are required for optimization, so computing MTF at all frequencies is not necessary. Within OpticStudio, MTF operands that compute MTF at a specific spatial frequency support a grid parameter that can switch between the grid method used by the graphics window and a fast, sparse-sampling method suitable for almost all optimization cases. The 2024 R2 release of Ansys Zemax OpticStudio brings productivity enhancements to the FFT MTF analysis feature. Multi-threading improvements for Fast Fourier Transform (FFT) Modulation Transfer Function (MTF) analyses enable more effective utilization of CPU resources for complex systems with multiple fields and wavelengths, with results showing a 67% decrease in total calculation time of an optical lens with a combination of 27 fields and wavelengths.
