ICC - The "Intensifier-coupled CCD Camera"

At ESA/SSD, we use LLTV (low lightlevel TV) cameras, also called Image-intensified cameras, to oberve meteors in the night sky. We are setting up two different camera types: The LCC series is a low-cost camera, the ICC is a state-of-the-art imaging system. Here, we describe the ICC. Figure 1 shows a block diagram of the camera.

The ICC camera series consists of the following elements:

  • Baffle - To avoid stray light entering the objective lens, and to reduce the probability of fogging of the lens
  • Objective lens - ultra-fast Rayxar lenses with different focal lengths:
    • 50 mm f/0.75
    • 90 mm f/?
    • 65 mm f/1.0
  • Lens heater - from Kendrick, operated on 12 V
  • Image intensifier - 2nd Generation MCP intensifiers with fiber input window from DEP, model no. XX1700DB. They operate on 3 V.
  • Sony XC-77CE Video camera, 2/3" CCD (directly coupled via fiber taper to output of intensifier), 756 (H) x 581 (V) pixels, 50 dB (12 bit) dynamical resolution, operating on 12 V.
  • Printed circuit board used as a fixture for cabling, also contains a 12 V to 3 V power regulator.
  • Connector for +12 V, ground, video output signal, shield
  • Mechanical housing (Aluminum, black anodized)
