The QHY174GPS camera is a remarkable scientific imaging device designed for precision and accuracy. Let’s delve into its features:

  1. Sensor and Specifications:

    • The QHY174GPS employs the Sony IMX174 CMOS sensor with a global shutter.
    • Key specifications include:
      • Pixel Size: Each pixel measures 5.86 μm x 5.86 μm.
      • Effective Pixels: It offers 2 megapixels.
      • Image Area: The effective image area is 11.25 mm x 7.03 mm (1/1.2-inch).
      • Frame Rate: It achieves a rapid frame rate of 138 FPS at 1920 x 1200 resolution.
      • Quantum Efficiency (QE): The QE is an impressive 78%.
      • Low Read Noise: The camera boasts a low read noise level of 3-5e-.
    • These specifications make it ideal for various scientific imaging tasks, including capturing occultations, eclipses, and meteors.
  2. Built-in GPS Module:

  3. Cooling and Anti-Amp Glow:

    • The QHY174GPS features dual-stage TE cooling, maintaining temperatures as low as -45°C below ambient.
    • It includes full anti-moisture control, including a heated optical window and a removable desiccant plug for the sensor chamber.
    • An anti-amp glow function significantly reduces the IMX174 sensor’s amplifier glow during long exposures.
  4. Global Shutter:

    • Unlike rolling shutter technology, the QHY174GPS employs a global shutter.
    • This ensures that the exposure time for the entire image area is uniform, starting and ending simultaneously.
    • Ideal for high-precision applications, it minimizes distortion caused by moving objects or atmospheric effects.

In summary, the QHY174GPS is a powerful tool for scientific imaging, combining precision, speed, and global shutter technology. Whether you’re studying celestial events or conducting research, this camera delivers exceptional performance

Global Shutter

Unlike the rolling shutter technology used in most CMOS cameras, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision applications. For high-speed moving object and the atmospheric agitation, the global shutter can generate undisborted imaging and realizes high picture quality.

Double Working Modes

Master mode:  In Master Mode, the camera is free running, and the internal 10MHz GPS synced clock will measure and record the shutter’s opening and closing time.

Slave mode:  In Slave Mode you can input a target start time and the interval period for two frames. For example: You want three cameras in different locations (maybe thousands of kilometers apart) to start an exposure at 2016.3.9.UTC 14:00:00.000000 and then to continue with exposures at the interval time of 0.100000 sec.  After you input these value, all the three cameras will wait until this time and then simultaneously start video recording, e.g.:

2016.3.9 UTC 14:00:00.000033

2016.3.9 UTC 14:00:00.100033

2016.3.9 UTC 14:00:00.200033

2016.3.9 UTC 14:00:00.300033

(The 0.00033 is a global delay of the CMOS shutter).

The time stamp and other GPS information is embedded into the image. The software decodes it in real time and displays the information on left.  Since the data is embedded, it will never be lost so long as you keep the original image.
