DRS’s Lightning ® RDT Plus ™ (Research, Design and
Test) camera combines high-speed digital video, intuitive camera
control software and powerful analytical functions with the
capabilities of a standard PC to provide an integrated, high-speed
imaging system with sufficient performance and flexibility to
address all motion analysis requirements.
Consisting of a small camera head, detachable cable and custom frame
grabber board, the Lightning ® RDT
Plus ™ captures 512 x 512 resolution images at 5,000 full frames per
second (fps). A blazing 100,000 fps can be achieved at reduced
resolution for recording extremely rapid events.
The Lightning ® RDT Plus ™ features extended recording times to
capture long duration events such as vehicle rollovers and missile
flights. More than 13 seconds of full resolution recording at 5,000
fps are available without compression. Greater than one minute of
record time can be achieved by reducing the frame rate to 1,000 fps.
The ability to daisy chain multiple frame grabber boards further
extends the record time.
A digital interface on the Lightning ® RDT Plus ™ custom frame
grabber board allows the output of a continuous, real-time stream of
digital image data. The digital interface is capable of streaming
image data at up to 1.25 gigabytes per
second—the maximum performance of the Lightning ® RDT Plus ™ camera.
The Lightning ® RDT Plus TM
is supplied with MiDAS software from Xcitex, allowing operators to
perform vital motion analysis, to control up to four cameras
simultaneously, and to save digital video data in different file
formats including AVI, BMP, JPEG and TIFF. Optional MiDAS modules
provide the synchronization of high-speed video with instrumentation
data from a variety of sensors, gauges, tachometers, IRIG encoders
and other devices.
The Lightning ® RDT Plus ™ is available with several distinct camera
head configurations: monochrome, color and low-light (for light
challenged environments). A single system can be purchased with
multiple, interchangeable camera heads, providing the flexibility to
record high-speed events in different situations.
