TTC ACT-1000-1 Stand Alone Active Camera Target
The ACT-1000 Active Camera Target is a standalone device intended for laboratory use and camera setup verification. The ACT-1000 time display consists of over 200 LEDs arranged as a 6-digit display, four 10 LED rows, and a 10 x 10 LED array. This display serves as a visual target for high-speed camera development and verification and for third-party camera testing. The display can be configured in a range of different time formats and resolutions. The LED array allows measuring camera exposure times from 1 sec down to 1 usec. The internal Real-time clock (RTC) automatically sets itself and tracks an externally provided IRIG-DC signal. This allows the device to act as a time slave to other ACT-1000 devices or to any other IRIG-DC time master. The RTC drives a microsecond counter, the LED display, and the IRIG-DC output time code generator and continues tracking time after the IRIG-DC input time source is no longer present or after the unit has been powered down. The RTC can also be manually set to any arbitrary time.
Independent brightness control of the different LED groups allows the ACT-1000 to compensate for different camera shutter speeds, providing a wide camera operating range. Several time reference outputs are provided, including a dedicated differential IRIG-DC, a dedicated one pulse-per-second (TTL), and two additional and independently configurable outputs. The outputs provide additional IRIG-DC, additional pulse-per-second, a 32.768 kHz clock, 10 MHz clock, and a fully-programmable synchronized pulse generator for driving external devices such as camera triggers or strobe lights.
The ACT-1000 setup is stored in non-volatile RAM, permitting the last setup to persist after power-down. The display is enclosed in a sturdy, black anodized aluminum case with a removable swivel bench-top base. Standard 3/8” and 1/4” tripod mounts are available. A universal AC/DC external power supply brick with a 9 ft. modular AC power cord is included.
The Need for Speed: Using Photogrammetric Analysis with High-Speed Cameras in Flight Testing Applications
Flight test engineers encounter situations where they need to use photogrammetric analysis to determine how objects, surfaces, and mechanical systems perform. This typically requires capturing images at high speed from multiple angles. Read this white paper to learn more about high-speed cameras and how they can provide users with the ability to conduct in-depth, quantitative analysis of their high-speed images.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
