The Relationship

A sine wave with high frequency and high voltage is a key driving signal for EMCCD to realize electron multiplication. According to signal requirements, DDS technique based on FPGA is employed and then sine-formed code-stream is converted to low-voltage sine wave by a digital/analog device. Afterwards, filtering and high-voltage amplification are used to acquire the sine wave with high frequency and high voltage. For the high-voltage amplification, the transfer function of the circuit system is used to correct the circuit parameters, and at last linear amplified sine wave signal with the functions of phase adjusting and amplitude controlling is obtained. By using the sine-wave to drive the EMCCD, low light level imaging is well acquired by the camera and the relationship between sine-wave amplitude and multiplication gain is tested.

Grin Lens

ICCD is one of the opto-electronic image sensors, commonly used in neutron low-light-level imaging system and the coupling of CCD and Image-Intensifier is the key technology in ICCD. This paper discussed the structure of ICCD, and simulated the coupling of relay lens, cone fibers and grin lens based on ZEMAX. We analyzed and checked their parameters such as geometric image, MTF, coupling efficiency, etc. Experimental results show that: The coupling of relay lens has high image quality; the coupling of cone fibers has high coupling efficiency; the performance of grin lens falls in between.
