Model 742DP Laser Spot Tracker

LONGWOOD, Fla., Dec. 6, 2010 — Analog Modules Inc. has released its patented laser spot tracker, Model 742DP, with wide flexibility for missile, unmanned aircraft systems, weapons systems and platform tracker applications.
The detector is temperature-controlled and optimized for 1.06 µm. Independent five-channel noise detectors set low thresholds to achieve long acquisition ranges for different background light and spot positions, and special circuits resist sunlight blinding in any or all quadrants. A range of N-type custom-designed detectors yields high performance.
A separate substrate allows the detector size or type to be optimized for a particular application. The hermetically sealed temperature-controlled detector with built-in front-end electronics is mounted on a surface-mount-technology board. A second printed circuit board contains analog and digital processing circuits. The individual channels are digitized with a high-speed analog-to-digital converter and output as a serial digital interface for steering. An adaptive threshold control allows optimum signal-to-noise operation, and power management reduces power consumption.
Responsivity at 1.06 µm is 0.4 A/W, bias voltage is 180 V, dynamic range is >100,000:1, and operating temperature is from -40 to 85 °C.
