Solid-State Spectral Light Source System

A solid-state light source combines an array of light-emitting diodes (LEDs) with advanced electronic control and stabilization over both the spectrum and overall level of the light output. The use of LEDs provides efficient operation over a wide range of wavelengths and power levels, while electronic control permits extremely stable output and dynamic control over the output.

Creating 3D Terrain Maps from 2D Data

Disaster relief workers, border patrol officers, wildfire fighters, and many others need up-to-date information about what they will see when they enter an area, not just sketchy topographic maps that may be years out of date. For them, things change in a hurry, and high-resolution details may be critical to their mission success.

Tunable Laser Module and Fast Spectral Loss Engine

Agilent Technologies (Santa Clara, CA) has introduced a compact tunable laser module for its 816x Series lightwave measurement platform. The Agilent 81960A module, which features a 200 nm/s sweep speed and increased acceleration, measures dense-wavelength division multiplexing (DWDM) components. The 81960A offers C- and L-band wavelength coverage for DWDM component measurements; it also provides bidirectional sweeping and 1-3 Hz repetition rate, depending on range. Automated measurements are supported by N7700A measurement engines, an updated 816x plug-and-play driver, N4150A photonic foundation library, and direct SCPI commands. The 81960A features up to +14 dBm output power, adjustable down to +6 dBm.

High-Dynamic-Range Read Out Circuit

The NSC1101 from New Imaging Technologies (NIT) Corp. (Verrières le Buisson, France) is a high-dynamic-range read out circuit (ROIC) designed to interface with photodiode arrays. The NSC1101 has a VGA format (640×512 pixels), and the ROIC offers a pitch of 15μm. Because of its Native Wide Dynamic Range™ of more than 120 dB, the sensor does not require any setting or exposure time control.
