In Chelmsford, Mass., !%McPherson Inc.%!, a manufacturer of dispersive spectrometers, has been contracted by Naval Air Systems Command (NAVAIR) for design and production of a spectral test, calibration and light delivery system. The Spectral Test System (STS) delivers near-contiguous wavelength coverage from the ultraviolet to the long-wave infrared. The system helps to characterize and document the response of sensors to specific wavelengths of light to calibrate their response and to acquire useful data when the spectral sensors are airborne. The STS will help NAVAIR to characterize sensors for the SPIKE program, a precision-guided technology using high-tech imaging and electro-optical sensors.
