The **HAS-D1-R/Q** series refers to specific high-speed, high-resolution digital camera systems (often associated with brands like DITECT) used primarily for motion analysis, production line monitoring, and research. Below is a detailed breakdown of the electronic components and technical specifications for these units. --- ### 1. Core Technical Specifications The primary difference between the **R** and **Q** models usually pertains to the sensor resolution and frame rate capabilities. | Feature | HAS-D1-R (Resolution Focused) | HAS-D1-Q (Standard/Balanced) | | :--- | :--- | :--- | | **Sensor Type** | CMOS (Progressive Scan) | CMOS (Progressive Scan) | | **Max Resolution** | ~1280 x 1024 (1.3MP) | ~640 x 480 (VGA) | | **Max Frame Rate** | Up to 2,000 fps (at full res) | Up to 8,000 fps (at full res) | | **Interface** | USB 3.0 or Gigabit Ethernet | USB 3.0 or Gigabit Ethernet | | **Bit Depth** | 8-bit / 10-bit | 8-bit / 10-bit | --- ### 2. Internal Electronic Architecture The system is built around several key electronic blocks that facilitate high-speed data capture and transfer. #### A. The Image Sensor (CMOS) * **Global Shutter:** Unlike rolling shutters found in standard cameras, the HAS-D1 electronics utilize a global shutter. This ensures that every pixel starts and stops exposure at the exact same time, preventing "jello" distortion in fast-moving objects. * **Pixel Size:** Large physical pixels are used to maintain high sensitivity (low noise) even at extremely short exposure times (microseconds). #### B. FPGA (Field Programmable Gate Array) * The "brain" of the camera. The FPGA handles the massive throughput of raw image data from the sensor. * It performs real-time tasks such as **Bayer pattern interpolation** (for color models), noise reduction, and formatting the data for the transmission interface. #### C. Internal Memory Buffer (DRAM) * High-speed cameras generate more data per second than a standard PC cable can handle in real-time. * The HAS-D1 contains internal high-speed RAM to store the video temporarily before it is "trickled down" to the PC. #### D. Input/Output (I/O) Logic * **Trigger Input:** An opto-isolated electronic circuit that allows the camera to start recording based on an external signal (e.g., a laser break or a PLC signal). * **Sync Output:** Allows multiple cameras to be electronically "daisy-chained" so they capture frames at the exact same microsecond. --- ### 3. Connectivity Components The electronic interface at the back of the unit typically includes: 1. **Communication Port:** USB 3.0 (for high-speed data transfer) or GigE (for long-distance cabling). 2. **Power Supply:** DC 12V input, often requiring a regulated power brick due to the high power draw of the FPGA during capture. 3. **Lens Mount Control:** Electronic contacts (depending on the specific build) for controlling motorized lenses or apertures. --- ### 4. Cooling System Because high-speed data processing generates significant heat, the electronic assembly includes: * **Active Cooling:** Internal fans and heat sinks attached directly to the FPGA and Image Sensor. * **Thermal Protection:** Sensors that throttle the electronics if the internal temperature exceeds safety limits.
