Kaman Measuring Highlights Family of Precision Measuring Systems for Free Space Optical Communication
Proven solutions for fast steering mirror control
The Measuring Division of Kaman Precision Products, Inc., the world leader in designing and manufacturing high-performance position measurement systems, highlights its family of precision differential non-contact eddy current measuring systems for free space optical communication. Widely used in commercial and military imaging and communication satellites, interplanetary exploration vehicles, laser targeting, night vision, and optics stabilization systems, the differential inductance transducer systems have a proven track record of outstanding performance. Kaman’s measuring systems provide reliable high-resolution position feedback, ensuring that a reflected laser beam finds its target hundreds or thousands of kilometers away. The differential measurement family includes the KD-5100+ high-reliability displacement system, the commercial grade DIT5200L differential impedance transducer, and the KD-5600 digital differential measuring system.
The KD-5100+ features a stable design, extremely small size, and low power consumption. It is ideal for laser communications satellites, ground stations, image stabilization systems, and directed energy systems for ground, shipboard, and airborne applications. With its small package size – only 2 x 2.12 x 0.75 inches thick – the KD-5100+ is ideal for meeting SWaP-C requirements. It is manufactured to Mil-PRF-38534 Class H, with MIL-SPEC components used throughout the electronics.
The KD-5600 digital differential measuring system features improved communication and convenience and highly accurate and easy-to-use precision. Kaman has combined its custom sensors, signal processing, analog-to-digital converter, and custom calibration system to deliver the precision KD-5690 system. This system provides digital, high bandwidth, and high linearity, with a high-end communication bus for fast data transfer.
Also on offer is the DIT-5200L, which offers a true differential for common mode rejection at an economical price. Capable of subnanometer resolution with high sensitivity (up to 10v/mil, 39 mV/μm) and outstanding linearity (up to 0.1 percent full range), this product provides a powerful solution for a diverse set of applications that demand exacting precision. The commercial-based, fully analog product is built to IPC A-160 Class 3 standards. Depending on the program requirements, it also offers commercial off-the-shelf screening opportunities. The I/O is on a 9-pin mini-D connector, and the input power connections are reverse voltage protected.
