The **HAS-D2-R** is a high-speed, high-resolution digital monochrome camera manufactured by **Ditect Corporation**. It is designed specifically for motion analysis, research, and industrial inspection where capturing rapid movements in high detail is critical. --- ## 1. Core Electronic Components & Specifications The electronic architecture of the HAS-D2-R revolves around its high-performance CMOS sensor and high-bandwidth data interface. | Feature | Specification Details | | :--- | :--- | | **Sensor Type** | High-sensitivity CMOS Image Sensor | | **Resolution** | 2.0 Megapixels (2048 x 1080 pixels) | | **Max Frame Rate** | 2,000 fps at full resolution (higher at reduced AOI) | | **Interface** | USB 3.0 (SuperSpeed) | | **Shutter System** | Global Electronic Shutter | | **Internal Memory** | Built-in high-speed buffer for frame capture | | **Bit Depth** | 10-bit / 12-bit Analog-to-Digital conversion | --- ## 2. Detailed Technical Breakdown ### A. The Sensor Engine Unlike standard cameras, the HAS-D2-R utilizes a **Global Shutter**. * **Electronic Function:** It exposes all pixels simultaneously rather than row-by-row (Rolling Shutter). This eliminates "jello effect" or spatial distortion when recording high-velocity objects like fan blades or projectiles. * **Sensitivity:** The sensor is optimized for low-light conditions, which is crucial because at 2,000 frames per second, the exposure time per frame is extremely short (micro-seconds). ### B. Data Processing & Connectivity * **USB 3.0 Bus:** The electronics utilize the USB 3.0 protocol for power and data. This allows for a "Plug-and-Play" setup without the need for expensive frame grabber cards. * **FPGA Control:** Internally, the camera likely uses a Field Programmable Gate Array (FPGA) to handle real-time image processing, triggering logic, and memory management before sending data to the PC. * **Synchronization (I/O):** The camera features external trigger ports (TTL level). This allows the electronics to sync with other cameras (Multi-camera setups) or external sensors (strobe lights, PLCs). ### C. Physical Integration * **Mounting:** Uses a standard **C-mount** interface for optical lenses. * **Housing:** Compact aluminum casing designed to act as a heat sink for the high-speed processing electronics. --- ## 3. Comparison of Resolution vs. Speed The electronics allow for trade-offs between the Area of Interest (AOI) and the capture speed: | Resolution (Pixels) | Max Frames Per Second (FPS) | | :--- | :--- | | 2048 x 1080 | 2,000 fps | | 1024 x 1024 | 4,000 fps | | 512 x 512 | 15,000 fps | | 2048 x 8 | 100,000+ fps |
