A linear CCD array is a simple device that takes a photograph of a moving object. Its design makes it ideal for outdoor use. The array's large-sized pixels are easy to store, and the CCDs have good dynamic range, meaning that it can capture many images in one second. As each photon passes through the system, it produces a charge that emitted by the object. The photon-induced charge is accumulated in the depletion region, which causes it to shift horizontally towards the camera's image sensor.
The smallest CCD in a linear CCD array has a 100-mA maximum output current. This allows it to be used in low-light conditions, but the smallest CCDs are only capable of detecting a few milliseconds of exposure, so they are inconvenient for nighttime observations. The best linear CCD detectors have a wide dynamic range and a linear pixel pitch of at least 20 mm.
A linear CCD array consists of a row of image sensor elements. Light is passed through the photosites and causes them to acquire a charge proportional to the illumination. The photosites then transfer these charge packets to an analog shift register (ASR) and charge detector. At the same time, another exposure is taking place. This process is repeated several times until the correct exposure has been achieved. However, there are some drawbacks to a CCD with this design.
A linear CCD array is an expensive investment, so it's important to find a detector that's right for your needs. The LARRY USB3648+ offers cost-effective performance and is compatible with most spectrographs. The LARRY series uses proven Ocean Optics electronics and software, so it's compatible with the spectrograph you're using. A standard PC connection is required, but if you need to integrate the LARRY USB3648+, you can opt to use GPIO communication.
The LARRY series is an example of an efficient linear CCD array. Its built-in electronic shutters can reduce integration time by as much as one microsecond. This makes the LARRY series particularly suitable for a wide range of applications. These cameras offer high-resolution images. A linear CCD array is often used in photography and other applications, but it is not an ideal choice for every application.
A linear CCD array consists of a row of image sensor elements. Each element has a charge detector. The light from the object illuminates a photosite. The charge from the photosite is transferred to an analog shift register. The digital signal from the charge detector is converted into a string of photo-dependent output voltage levels. The image is then stored in the memory of the sensor and stored. When the pixel receives an exposure, the entire system continues to acquire a charge.
The MLX90640 SparkFun IR Array Breakout is a low resolution thermal imaging camera with a 32x24 thermopile array. It is capable of detecting temperatures with accuracy +1.5 degC from up to a few feet away. The device communicates with the host platform through I2C. The pins are 0.1" apart, which makes for an easy connection.
The IR Array Breakout has a field of view of 55degx35deg. Its temperature measurement range is -40 degC to 300degC. The sensor's I2C bus is attached to pull up resistors, which make it easy to connect to a host platform. However, the IR Array requires complex calculations from the host platform, and a regular Arduino Uno doesn't have enough RAM to process these calculations. The Teensy 3.1 is recommended for this project.
