As high-speed imaging systems have evolved over time, customers have begged for
more speed and higher resolution. If this was an easy accomplishment, fast mega- pixel cameras would have been offered several years ago. After all, fast camera designs are abundant, and high resolution cameras are now commonplace even at the consumer level. The real challenge is in developing a system that offers both of these qualities. This is a difficult design task, and other critical parameters such as light sensitivity further complicate the issue of developing a fast, truly high resolution imaging system that is compact, user-friendly, and affordable.

12 bit SR-CMOS technology

VRI's latest response to this speed/resolution challenge is our new Phantom v9.0. The v9.0 supplies high speed recording along with resolution and image quality that would have been considered impossible to achieve just a short time ago. Digital camera resolution is largely dependent on the number of pixel elements on the sensor, and the v9.0 has the highest pixel count of any high-speed camera in the industry (approaching 2 million). Our breakthrough design SR-CMOS sensor is composed of 1,600 x 1,200 pixels and offers a recording speed of 1,000pps using this full array! Yes, these are real pixels, not numbers derived from software routines that add "virtual" pixels to the actual count. The v9.0 sensor includes several new features, but it also continues to offer all of the "on-chip" advantages of our previous designs such as a global shuttering, Extreme Dynamic Range? (EDR) to improve picture quality under harsh lighting conditions, auto exposure, and much more.

1600×1200 pixel resolution

The v9.0's CMOS sensor offers a 4:3 full frame aspect ratio (the proportions of a the standard TV screen) composed of 1600 x 1200 pixels. Using our "CAR" (Continuously Adjustable Resolution) feature, the active image area is adjustable in 48x2 pixel increments. This allows the operator to maximize the field of view by closely matching shape and dimensions of the test subject in the horizontal and vertical plane. Using this precise adjustment in combination with infinitely variable settings for other operating parameters allows you to fine tune your setup with more accuracy than with the preset choices found on some other systems. This flexibility allows the user to optimize recording speed, exposure, and recording time for the exacting requirements of each test. As always, these settings can be saved using the Phantom software allowing you to duplicate setups for recurring tests.

1,000 pictures per second full frame

The Phantom v9.0 offers a recording speed of 1,000 full frame pictures per second. When reducing the aspect ratio (image size) to 960x960 the speed jumps to almost 2,000 pps, and there are allocations to record at even higher speeds with further decreased image sizes. Our extremely popular and until now, our highest resolution camera system, the award winning Phantom v5.0, records 1,000pps at a resolution 1,024x1,024, and the new v9.0 has virtually doubled this rate!

Color or Monochrome models

In addition to higher resolution, overall image quality from both the monochrome and color v9.0 is outstanding. The color version of the v9.0 uses a slightly different color filter array than our previous sensor designs, and new demosiacing algorithms in our software increase color performance for the v9.0 and for all product models.

Regardless or your choice, color or monochrome, the v9.0 will produce images that far exceed anything expected from previous digital "high-speed" imaging systems. The
v9.0 supplies images that will meet, or depending on the format, exceed the quality of
high speed film.

2 micro second exposure

An extremely fast shutter, adjusted independently of the recording rate, controls image blur. The v9.0 offers continuously adjustable shutter speeds down to 2 祍ec (1/500,000 second). This shutter is a true "snap shot," or "global" shutter, functioning at the pixel level. Fast recording times and shutter speeds are meaningless if the sensor's light sensitivity is too "slow" make pictures during the brief period of time that is available to build a charge. The v9.0 sensor is the most responsive in its size class, and maximum frame rates and short exposure times can be achieved with minimal light levels.

Gigabit Ethernet, Firewire, or RS232/422

A PC compatible laptop or desktop computer running the Phantom software package, included with each camera purchase, controls communication with a single, or multiple networked cameras . A new Gigabit Ethernet interface is now standard in v9.0, in addition to the proven choices of IEEE 1394 FireWire? or RS232/422 communication interface for setup, control, viewing images, analysis, and download of image files. Using the FireWire interface a single computer can control up to 63 cameras, and optional remote links using cable or optical fiber are available to extend the working distance between the camera control computer to the camera. Our new Multi IOIOI acts as a junction box to simplify the setup and operation of up to four cameras, and they can be chained to further expand the network. The v9.0 can also be controlled with a Palm PDA. Our Phantom software insures v9.0 compatibility with all previous camera models from the v4.0 and up.

Continuous data stream

High-speed events are typically very short in duration even if they take place flexible unexpectedly over a long period of time. By taking advantage of the Phantom's triggering capabilities in combination with extended internal memory options, 99% of our customers have the recording time they need for any application. In fact, after the files are edited to include just the brief moment of interest, much of the cine may actually be discarded to save storage space.

But sometimes there is a valid requirement for long recording times. As an option both the Phantom v9.0 and v7.0 can be supplied with the ability to stream real-time image data to an external massive storage device. This is not an off-the-shelf solution at the current time because of unique customer requirements and their vastly differing preferences for storage hardware. If this is a requirement for your application, let us know so we can discuss your requirements to maximize your options. Our customers who record rocket launches and work with aircraft mounted cameras will see many of their problems solved with this unique capability.

Our Phantom cameras were the first digital systems with the ability to accept and The modulated or un-modulated IRIG-B timing. The v9.0 can be locked to the IRIG signal, multiple cameras can be variably phase shifted from one another to extend coverage. v9.0 also accepts range data input to record information for other instrumentation i.e. azimuth/elevation data from a tracking mounts etc.

If you have been looking for film quality images with speeds fast enough to meet you're most demanding test requirements, take a serious look at the Phantom v9.0.
