CCD Liner Cameras

CCD Liner Cameras

The linescan photodiode array is a Pinned Photodiode Charge Couple Device which allows for high sensitivity, fast readout, while maintaining high dynamic range, and low image lag.
Technology From: Excelitas Technologies

CCD Liner Cameras

SmartBlue™ digital linescan cameras incorporate the latest in photodiode array technology based on the industry standard Reticon® devices with state of the art electronics and a robust industrial camera housing. The linescan photodiode array is a Pinned Photodiode Charge Couple Device which allows for high sensitivity, fast readout, while maintaining high dynamic range, and low image lag.

SmartBlue™ cameras are cost effective high performance digital linescan cameras, and feature a CameraLink™ digital interface. These cameras feature geometrically precise photodiode CCD image sensor with 14 um square pixels with a resolution of 2048 pixels. This "next generation" array can achieve data rates up to 80 MHz with superior noise immunity, precise linearity, and high CTE.

They are designed for high line rate applications with low to moderate light conditions and where small size, and low cost are required.

The two-point Flat Field pixel correction circuits give the user the flexibility of correcting video data to compensate for non-uniformities in lighting, lens, or CCD sensor variations. Adjustable gain and offset controls allow users to compensate for variations in illumination found in the "real-world" applications.

The robust design in conjunction with ultra-modern manufacturing techniques allows the SmartBlue™ camera to deliver consistent, reliable performance while the rugged industrial design metal housing provides the maximum protection in a variety of harsh environments and factory floor conditions.

CCD Linear Imagers

CCD Linear Imagers

Warsash Scientific offer an improved version of the industry standard P-series -712 linear array, the -012. The -012 version represents the latest in CCD technology.
Technology From: Excelitas Technologies

CCD Linear Imagers

Warsash Scientific offer an improved version of the industry standard P-series -712 linear array, the -012. The -012 version represents the latest in CCD technology. Users can expect increased sensitivity and efficiency in all specified wavelengths, increased capacity to collect, store, and transfer data, lower noise across the imager, all the while consuming significantly less power and in a pin-compatible configuration with their existing -712 P-series sockets.

A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time. Technically, CCDs are implemented as shift registers that move charge between capacitive bins in the device, with the shift allowing for the transfer of charge between bins.

X-Ray Photodiode Arrays

X-Ray Photodiode Arrays

The listed designs can be ordered as a standard part, but can also be customised to meet the needs of a wide variety of applications.
Technology From: Excelitas Technologies

X-Ray Photodiode Arrays

These photodiode arrays are used to generate an X-ray image by scanning an object line by line. The X-rays are converted into light through the attached scintillator crystal. The light intensity is then measured by the photodiodes. The boards are employing chip-on-board technology with optically adapted scintillator crystals. The listed designs can be ordered as a standard part, but can also be customised to meet the needs of a wide variety of applications.

Custom photodiode arrays give customers the option to choose the:

  • Active photodiode area
  • Total number of elements
  • Overall PCB and photodiode chip dimensions
  • Photodiode chip geometry and orientation
  • Electro-optical specifications
  • Single sided vs. double sided PCB
  • Alternative substrate materials (e.g. ceramic)
  • Electrical interface (e.g. connector)

First stage amplification electronics can also be added to the custom board design to convert the current generated by the photodiode into an easy to measure voltage.

Thermopile Array Modules

Thermopile Array Modules

These thermopile modules are based on silicon micromachining technology.
Technology From: Excelitas Technologies

Thermopile Array Modules

These arrays include detectors composed of several thermocouples typically connected in series. They are DC-type detectors and, thus, best suited for non-contact temperature measurement. These thermopile modules are based on silicon micromachining technology. A special IR-absorption layer covers the hot junctions, creating the sensor's sensitive area.

Thermopile linear arrays with digital interface consist of a thermopile line/matrix array sensor with integrated ASIC, E2PROM, a microcontroller with integrated 10-bit analogue-to digital converter for signal processing and interfacing.

The microcontroller controls the multiplexer of the thermopile line/matrix sensor as well as all internal operations. These include measurements and calculations for the object, ambient temperatures and post-processing of the temperatures to output them via a digital serial interface (SMBus). The temperature-dependant signal of the thermopile line array elements is subsequently fed through an analogue-input multiplexer into a low noise, low offset chopper amplifier with constant gain. The amplified thermopile signal, a voltage reference signal and the signal from the on-chip integrated PTAT (ambient temperature) sensor is connected to an output multiplexer which alternately feeds the signals to the analogue digital converter (ADC) of the microcontroller.

After analogue-to-digital conversion, the resulting digitised voltage signals are stored in the microcontroller's RAM. Based on the calibration settings stored in the TPLM's E2PROM and on the described measurement results, ambient temperature voltage signal (VTamb) and normalised voltage signals for individual pixels (Pi) are calculated from the raw signals.

An SMBus-compatible, two wire bidirectional serial interface is provided to read out the sensor's temperature signals and for Read/Write access to the sensor's configuration data and calibration parameters. The SMBUS allows connection of a master device (MD) and one or more slave devices (SD).
