In order to improve the measurement accuracy of optical detection instruments temperature control circuits for narrow band-pass filters are given and the error analysis is applied to temperature control circuits.The principle of a temperature measurement circuit is studied and the method of a driver circuit is described. A variety of influencing factors of temperature control accuracy are discussed. Moreover for these error factors improvement measures are given to reduce the nonlinear error. Finally circuit parameter error is quantified to propose a calculation method for margin of error in a temperature control system. (2013) Trans Tech Publications Switzerland.

There exist complex gray mapping relationships among infrared and visible images because of the different imaging mechanisms. The difficulty of infrared and visible image registration is to find a reasonable similarity definition. In this paper, we develop a novel image similarity called implicit linesegment similarity(ILS) and a registration algorithm of infrared and visible images based on ILS. Essentially, the algorithm achieves image registration by aligning the corresponding line segment features in two images. First, we extract line segment features and record their coordinate positions in one of the images, and map these line segments into the second image based on the geometric transformation model. Then we iteratively maximize the degree of similarity between the line segment features and correspondence regions in the second image to obtain the model parameters. The advantage of doing this is no need directly measuring the gray similarity between the two images. We adopt a multi-resolution analysis method to calculate the model parameters from coarse to fine on Gaussian scale space. The geometric transformation parameters are finally obtained by the improved Powell algorithm. Comparative experiments demonstrate that the proposed algorithm can effectively achieve the automatic registration for infrared and visible images, and under considerable accuracy it makes a more significant improvement on computational efficiency and anti-noise ability than previously proposed algorithms.
