WAYNE, N.J., Nov. 23, 2010 — Vision Research has unveiled the Phantom v341, a high-speed digital camera tailored to military, scientific, research and range applications.
Its light sensitivity is rated at 4000 ISO (monochrome, ISO 12232 SAT method). High-light sensitivity results in better performance in natural light and in self-illuminating tests, as well as lower costs for purchasing and operating supplemental lighting.
The camera incorporates a 4-megapixel 35-mm-format sensor and offers almost 3-gigapixel/s throughput, enabling full-resolution rates of 800 fps. Shutter speeds down to 1 µs and a global electronic shutter allow for crisp, sharp images with little or no image blur or motion artifacts.
The wide field of view is a result of the custom-designed 2560 × 1600-pixel CMOS sensor in color or monochrome. The aspect ratio allows users to keep moving targets in-frame longer and to see more of the event they are recording.
This "range ready" camera has dual power inputs to protect data in case of power failure (via battery backup), time code in/out (IRIG or SMPTE), and range data input allowing the user to capture azimuth and elevation data for each frame. Additional features – such as a new reflective color, remote current session references through software control, and an optional Canon EOS lens mount – enable complete remote control, making the compact and lightweight camera suitable for outdoor shooting in environments when easy access to the camera is not possible.
Several convenience features, including an internal mechanical shutter, image-based autotrigger, optional on-camera controls, and the CineMag interface make the camera suitable for range applications, and its overall portability is convenient for tracking mount applications.
With peak quantum efficiency of 60% and a significant reduction in readout noise, the camera’s 4-megapixel resolution can be used to full advantage at speeds that normally call for large-pixel and lower-resolution cameras. Coupled with 2.5-µs straddle time, the camera is suited for particle image velocimetry applications. In burst acquisition mode, it can take a user-selected number of frames after receiving a single frame synchronization pulse, simplifying timing setups for repetitive events such as combustion cycles.
Users will benefit from the camera’s options for storing and protecting data. With its dual power inputs, data protection is ensured via battery backup (optional) in case of power failure. In addition, the CineMag interface gives users the option to continuously record directly to the nonvolatile hot-swappable Phantom CineMag memory magazines at 128, 256 or 512 GB, and then connect to CineStation to view, edit and save cines. If waiting to watch recorded cines is not an option, recordings can be viewed immediately via two identical 4:2:2 HD-SDI ports for previewing a shot or viewing full recorded cines.
Features include operation from 10 to 800 fps at full resolution, with a maximum of 129,500 fps at 256 × 8-pixel resolution, and memory segmentation of up to 63 segments. The high-resolution timing system delivers better than 20-ns resolution. The extreme dynamic range function provides two different exposures within a single frame.
Additional features include built-in 8-, 16- or 32-GB memory, pixel depth of 8- and 12-bit, a Gigabit Ethernet interface, analog video output in PAL, NTSC and HD Component, and F-, C- and PL-mount lenses.
