In order to solve the problem of precise temperature control  the thermoelectric cooler (TEC) principle widely used is analyzed for the design of the whole control process and selection of control parameters  and then accurate simulation model of the TEC is established in Proteus simulation software. Moreover  combined with the traditional circuit simulation model  the temperature control loop is designed  and the response characteristics of the system are tested using an input signal similar to the unit-step function to achieve the precise temperature control. Simulation results show that the proposed control circuits can precisely convert error signal to output voltage sent to TEC model  and TEC model behaves approximately like a two-pole system. The first pole starts at 20mHz and a second pole at 1Hz. 2011 IEEE.

Pre-amplifier circuit is critical for the noise performance of the high speed CCD camera. Its main functions are amplification and impedance transform. The high speed and low noise pre-amplifier of CCD camera is discussed and designed in this paper. The high speed and low noise operational amplifier OPA842 is adopted as the main part. The gain-set resistors for the amplifier are designed optimally. The different precision gain-set resistors are swept using Monte Carlo method. CCD video signal which has high DC offset voltage is AC coupled to the amplifier. The output signal of the amplifier is source terminated using 50 ohms matching resistor so as to transmit the video signal through coaxial cable. When the circuit works in high speed  the PCB will have important effect to circuit performance and can even cause the amplifier unstable due to the parasitic problem of PCB. So the parasitic model of the PCB is established and the PCB layout design issues are also presented. The design result shows that the pre-amplifier can be used in the camera whose pixel rate could be up to 40 MHz and its input referred noise density is about 3 nV/Hz 1/2. 2010 Copyright SPIE - The International Society for Optical Engineering.

The remarkable improvement of sensing and processing hardware performance makes the non-contact  on-line  high accuracy and high speed measuring possible by means of linear CCD. The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular  the factors affecting accuracy  such as resolution  voltage difference between neighbor pixels  detecting rate and so on  are analyzed  and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions  so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion  several principles that can be used to improve the boundary recognition accuracy are presented.
