Photo Integrated Circuits

Hamamatsu Corp. (Bridgewater, NJ) offers a transmitter-receiver pair of photo integrated circuits (ICs) for use in MOST-compliant automotive multimedia networks. The L10063-01 transmitter and S10064-01 receiver provide a maximum data communications rate of 50 Mbps over plastic optical fiber links. The transmitter offers an operating mode that reduces the optical output level by half, reducing power consumption. The receiver has a low-power-consumption “sleep mode” and can shift into normal operating mode by detecting a light trigger. The receiver also features a wide dynamic range and is immune to external noise. Both components are housed in a clear plastic package and have an operating temperature range of -40°C to +105°C. Signal transfer between the components is performed digitally via a TTL interface.

Ethernet CCD Camera

The TM-1405GE from JAI PULNiX (San Jose, CA) is a high-resolution, 1.4-megapixel CCD camera. The interline transfer CCD permits full vertical and horizontal resolution with shutter speeds up to 1/16,000 sec. Asynchronous test, combined with a no-delay, pulse-width controlled shutter, provides flexible triggering and exposure control for machine vision applications. The camera is combined with a standard 1/2" image sensor and captures 30 frames per second at full resolution of 1392 × 1040. The camera features 100-meter cables, standard ports, and a look-up table that allows full dynamic range control of the CCD by externally selectable knee slopes. The camera has both digital Gigabit Ethernet and analog output for interfacing with other equipment.

Pulsed Fiber Laser

Lumics (Berlin, Germany) has introduced the LU1060F400 pulsed fiber laser that offers up to 0.8 mJ pulse energy with average power of 4W. It is a short-pulse Ytterbium fiber laser in Master Oscillator Power Amplifier (MOPA) configuration. The laser operation mode can be changed by selecting customer-specific parameters, such as output power, pulse energy, repetition rate, and pulse width, via a conventional USB interface. The laser emits at a wavelength from 1060 to 1080 nm from a fiber with a 25-um core. The fiber is a standard length of 1.5 m, terminated with an FC/APC connector. An optional collimator and focuser, as well as metal armored cable, are available.

Image Analysis Software

Sensors Unlimited, Goodrich Corp. (Princeton, NJ) has released SUI Image Analysis Software, which allows full operational control of the high-speed windowing functions on the SU320MSW-1.7RT Shortwave Infrared (SWIR) Windowed Snapshot MiniCamera, and the SU640SDWH-1.7RT High-Resolution SWIR Windowing Camera. The standalone, executable software options include full control of four preset regions of interest or windows, in the center of the frame. Variable windows can be established through the software interface. The user may select position, size, and shapes, and may perform image enhancements on captured images and save the images in a movie format with or without NUCs and/or enhancements.

Fiber-Optic Laser Couplers

Bristol Instruments (Victor, NY) offers the LC Series fiber-optic laser couplers that can be used to launch a free-space laser beam into a fiber, or return the laser to a collimated free-space beam. The couplers contain a 1"- diameter mounting disk attached to 3 meters of 9-μm core-diameter fiber that is terminated with an FC/PC connector. The LC-1 input coupler includes built-in alignment optics that provide two slightly off-axis back reflections to facilitate alignment. With the LC-1 installed in a standard theta-phi optical mount, alignment is achieved by centering the laser beam on the input aperture, and then adjusting the mount so that the two back reflections straddle the input beam symmetrically. The LC-2 output coupler is identical to the LC-1, but without the alignment optics. It is used to return the laser to a collimated free-space beam.

Wide-Gap Sensor

TT Electronics OPTEK Technology (Carrollton, TX) offers the OPB856Z Series wide-gap optical sensor that includes an emitter-sensor pair. The sensor consists of an LED and a phototransistor designed to operate over distances of 12" in industrial environments. The sensor components are mounted in threaded, color-coded housings; the LED (white housing) and phototransistor (black housing) are designed for panel mount through a 12-mm hole, with a corresponding nut included for each housing. The emitter-sensor pair is designed to electrically mate with a Molex 03-06-2023 connector with either male for the LED or female for the sensor pins.
