Contactless Laser Extensometers
Jinan Testing Equipment IE Corporation
Model LE-05 and LE-15 extensometers measure strain optically, without contacting the specimen, using laser diode technology. The extensometers are self-contained and portable. They may be interfaced with a variety of testing machines and data acquisition systems using the ±10V analog output or bi-directional RS-232 serial port. Operation may be local or remote. A digital display is included. The scanning beam is always perpendicular to the specimen, unlike most laser extensometers. This eliminates errors when viewing through windows in chambers. It also minimizes sensitivity to the distance between the extensometer and the sample. Because the unit measures reflected light, no receiver is required behind the sample.

Audio Fiber Tracer
CFT-810
Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient ‘save and recall’ functions. As a Scanning PC, it provides very powerful ‘auto scan’ modes with variable scanning speeds. Polarization states can be manipulated by either manual adjustment or remote control (GPIB, RS-232) using two quarter-wave plates in each channel of the PC1600. Additionally, the auto scan mode of FIBERPRO’s Motorized Polarization Controller has been upgraded in LPC, and it shows another auto scan mode of four quarter-waveplates with higher polarization extinction ratio when connecting two channels at a high speed. PC1600 is an essential tool to complete fiber-optic, multi-channel measurement systems such as WDM/DWDM as well as R&D (i.e. PMD experiments), and manufacturing.

Protocol Converter
MACC2
When designing or upgrading avionics systems we are often faced with the task of integrating components that were not originally designed to work together.A control computer that communicates using RS-232 may need to control component that expects MIL-STD-1553 messages or an INS may put out ARINC-429 labels, which are needed by Multi function Display designed around RS-422.Faced with problems like these, integrators must choose between two poor options. They must either give up on one of the units in favor of another unit that may be less suitable but uses the appropriate communications spec; or they must add a computer system – often PC104 – which can translate from one unit to the other. These computers are generally large, heavy, hot, and require substantial power.
