120829-N-HW977-040 NORCO, Calif. (Aug. 29, 2012) Naval Surface Warfare Center (NSWC), Corona Division Microwave/Electro-Optic (MS32) Electronics Engineer Daniel King aligns various optical components using visible lasers. Under the Navy Metrology Research and Development Program, NSWC Corona’s E-O Group has developed and patented two calibration standards for support of laser designator and rangefinder test sets. The Laser Transmitter Support Standard (LTSS-300), a calibrated laser energy and pulse width source, is used at variable high power levels for 1064 nm, and the Dual Wavelength Low Level Laser Radiometer (D-ESR), which ensures accurate measurements of pulsed lasers at 1064 nm and 1550 nm wavelengths, keeping ordnance on target and reducing the cost of maintenance for the fleet.

Nuts & Bolts: The subject, a specialist in designing laser calibration equipment for the Department of Defense, and I discussed experimenting with this, so when he needed some photos for a PowerPoint presentation he would be giving, the time was ripe to see if we could make it happen. Main light was a speedlite on the keyboard of a laptop at left, while another speedlite was placed out of frame at right to illuminate the equipment arranged on the optical bench. Once the subject saw the flash, he activated a smoke machine, using the wired remote in his left hand, wafting smoke across the stage during the remaining eight seconds of the exposure. The photo required quite a bit of teamwork: We had others in the darkened room helping us, one working the lights and another waving a sheet of foamcore to dissipate the smoke between exposures.
