The new device acquires a projection profile in the x and y axes to provide high-speed position and moving object detection, even from very small amounts of information. It has a 256 × 256 pixel array with a 1.9968-square millimeter active area. Images can be produced at 1.2 ms per channel when in an 8-bit mode, or 2.4 ms/channel in a 10-bit mode. The S9132 covers a spectral range of 350 to approximately 1150 nm, and achieves a peak sensitivity of 40 V/nJ (high gain) or 8 V/nJ (low gain) at 780 nm. The device chip incorporates a timing generator, bias-voltage generator, and an 8-bit/10-bit switchable A/D converter.

The standard model (3363-A) incorporates an adjustable voltage-controlled-oscillator (VCO) frequency source available from 25 MHz to 1 GHz. The VCO source can be manually tuned over one octave (typically) or the VCO frequency can be set to track the resonant peak of the EOM. In the models 3363-B and -C, a synthesized frequency source stabilized to a crystal oscillator can be furnished for the frequency range 50 kHz to 2 GHz. The instrument’s RF amplifier provides approximately 30 dbm of power, sufficient to drive any of the resonant EOMs to a modulation depth beyond three radians or to achieve three radians of phase modulation.

Using these two-color photodiodes, unknown temperatures are measured by taking the ratio of radiation intensities of two adjacent wavelengths and comparing them with the standard blackbody radiation curves. The sandwich detectors are independent of emissivity and are unaffected by moving targets or contaminants in the field of view. The dual-sandwich detector types include a silicon-stacked-on-silicon; a silicon-indium gallium arsenide version that extends the wavelength range; and a Si-InGaAs device that incorporates a thermoelectric cooler for improved accuracy. Applications include flame temperature-sensing, spectrophotometry, and IR temperature monitoring.

MonoCL SP can be configured for almost all scanning electron microscopes, microprobes, and analytical transmission electron microscopes. It features a new design of spectrometer that has a fixed-position grating to disperse the collected CL over a wide CCD array; the 20-µm CCD pixel size enables high spectral resolution. The cooled CCD camera allows fast acquisition of a CL spectrum to minimize charging of or beam-induced changes to the specimen. MonoCL SP includes panchromatic CL imaging to provide imaging with high spatial resolution and is supplied with the company’s Digital Micrograph software with CL plug-in.

Its energy conversion efficiency is 99.7% (within the Fermi–Dirac profile) and 75% within the flattop, with 10% rms power variation. The Refractive Beam Shaper functions over a large spectral bandwidth, from 250 to 1600 nm (depending on coating depth), and produces no hard edges, speckles, or diffraction effects. The device incorporates a unique refractive optical design and technology, patented by IBM Research, that has enabled applications in illumination, laser processing, and nonlinear optics, and when light-focusing requirements are necessary, such as in microscopy and printing.

The company’s line of MEMS DMs is based on thin-film silicon membrane technology. DMs are adaptive optics that have the ability to compensate for poor optical quality of the light reflecting from them. The Clarifi system includes a 16-mm-diameter, a 37-actuator silicon DM; a CCD video camera; a video frame grabber, a 32-channel mirror driver and interface box; a PC with a Microsoft Windows XP operating system; and software that offers the choice of eight feedback metrics and five convergence algorithms. The control loop can be set to run a single convergence or to continuously update the DM surface for dynamic applications.

Because the information of interest is encoded with the wavelength of that signal, that measurement is critical. In the FBG monitor, the interference fringe pattern of the reflected signal—at a wavelength within the 1520- to 1620-nm band—is compared to that of a built-in wavelength standard; the accuracy of the measurement is ±1.5 pm.The sensors measure environmental conditions such as temperature, pressure, and strain, and possess advantages for remote sensing because they are environmentally stable, offer higher-accuracy measurements, and have a longer lifetime.
