The Photron Crysta PI-1P polarization high speed camera is used to quantify and measure physical stress in transparent and semi-transparent fluids and solids. The Photron Crysta PI-1P polarization camera system can measure at 7,000 fps in full resolution operation or at 1.3 million fps when running at reduced resolution.
The Photron Crysta PI-1P high-speed polarization camera for the two-dimensional analysis of birefringence measurements, film thickness analysis, and surface roughness inspection, and is a powerful tool to understand phenomena such as birefringence, retardation, stress and impact fracture mechanisms of materials and fluids. This systems employ mechanical or electrical drives as polarization modulators, they require several photo-detection processes to measure polarization. In order to overcome this problem, The Photron Crysta PI-1P utilizes a high-speed 2D birefringence measurement system with a sampling rate of 1.3 MHz as the core device of the system with 16 parallel read out circuits in a matrix in the image sensor, which are connected to each pixel with individual A/D converters.
The image sensors design and fabrication incorporates a pixelated polarizer array which is made from photonic crystal bonded directly to the CMOS sensor, making the optical system in this sensor resistant to vibration. Each polarizer corresponds to each pixel of the image sensor with a one to one ratio. The size of each polarizer and pixel is 20 µm x 20 µm. In the polarizer array, groups of four neighboring polarizers (2 x 2) are set to have differing fast axis orientation at 0°, 45°, 90° and 135° in a clockwise arrangement. One polarization datum can be obtained by calculating detected light intensities from the four pixels of the image sensor. The parallel read-out circuit is arranged in a corresponding matrix.
The electric charges that represent the light intensities accumulated from each pixel are quantized by the multi-channel Analog/Digital converters and are stored in the memory of the camera. Once that is done. the software apply a phase shift analysis process to the stored data to obtain time-serial images of birefringent phase difference.

How To Choose Your MWIR Infrared Camera
When it comes to selecting the right mid-wave infrared (MWIR) camera for your specific needs, understanding the technology and its applications is crucial. MWIR cameras are powerful tools that capture thermal images in the 3 to 5 micrometer wavelength range, making them ideal for various applications, including industrial inspections, scientific research, and defense surveillance. This guide will walk you through the essential factors to consider when choosing an MWIR camera, ensuring you make an informed decision.
What is MWIR?
Mid-wave infrared technology refers to the imaging capabilities that operate within the 3 to 5 micrometer range of the infrared spectrum. This range is particularly effective for detecting thermal radiation emitted by objects at moderate temperatures. MWIR cameras are designed to capture this thermal energy, converting it into visual images that can be analyzed for various applications.
How MWIR Cameras Work
MWIR cameras utilize a combination of lenses, thermal sensors, and processing electronics to create thermal images. The lens focuses infrared radiation onto the detector, which is typically an array of pixels. These detectors can vary in resolution, with common configurations being 320x256 and 640x512 pixels. The thermal energy absorbed by the detector is then converted into an electronic signal, which is processed to produce a visual representation of the thermal scene.
Advantages of MWIR Cameras
- Sensitivity: MWIR cameras are known for their high sensitivity, allowing them to detect subtle temperature differences in a scene. This is particularly beneficial for applications requiring precise thermal measurements.
- Versatility: These cameras can be used across various industries, including manufacturing, environmental monitoring, and military applications, making them a versatile choice for many users.
- Image Quality: The ability to capture detailed thermal images enables users to identify issues that may not be visible in the visible spectrum, such as heat leaks in buildings or overheating machinery.
Key Considerations When Choosing an MWIR Camera
1. Application Requirements
Before selecting an MWIR camera, it's essential to define the specific application for which it will be used. Different applications may require different features and capabilities. For instance:
- Industrial Inspections: If the camera will be used for detecting heat loss in buildings or monitoring machinery, high sensitivity and resolution are critical.
- Scientific Research: Researchers may need cameras with advanced features such as multispectral imaging or high dynamic range capabilities to capture a broader range of data.
- Defense Surveillance: In military applications, the ability to detect and identify targets at long distances is paramount, necessitating high-resolution imaging and fast frame rates.
2. Resolution and Sensitivity
The resolution of an MWIR camera determines the level of detail that can be captured in thermal images. Higher resolution cameras can provide more detailed images, which is crucial for applications requiring precise measurements. Additionally, sensitivity, often measured as Noise Equivalent Differential Temperature (NEDT), indicates the camera's ability to detect small temperature differences. A lower NEDT value signifies better performance, especially in applications where subtle temperature variations are critical.
3. Cooling Requirements
MWIR cameras can be categorized into two types based on their cooling requirements: cooled and uncooled. Cooled MWIR cameras typically require cryogenic cooling to operate effectively, which enhances their sensitivity but adds complexity and cost. Uncooled MWIR cameras, on the other hand, can operate at ambient temperatures, making them more compact and easier to use. When choosing a camera, consider the trade-offs between sensitivity and operational simplicity.
4. Environmental Conditions
The environment in which the MWIR camera will be used plays a significant role in the selection process. Factors such as temperature extremes, humidity, and exposure to dust or moisture can impact camera performance. Ensure that the chosen camera is rated for the specific environmental conditions it will encounter.
5. Budget Constraints
Cost is always a consideration when selecting any technology. MWIR cameras can vary significantly in price based on their features and capabilities. It's essential to balance your budget with the required specifications to ensure you get the best value for your investment. Consider not only the initial purchase price but also the long-term operational costs, including maintenance and potential upgrades.
