“…With wide spread use of photoelectric autocollimator, there is also a high requirement of precision and convenience, especially in field of aeronautics and astronautics, machine manufacturing, measurement facilities and scientific research [1] which have specially high request of precision. Current autocollimators have following two defects: measurement errors inevitably exist as result of human aiming to read; line imaging sensors cannot precisely reflect two-dimensional angular displacement [2,3].…”

The paper explains an auto-read photoelectric autocollimator based on DSP and area array imaging sensors. The working principles, hardware and software of the design is interpreted. This equipment is able to conduct precise two-dimensional measurement. The embedded core Blackfin DSP BF549 is used in the device to acquire consecutive video, help store them and process the image datas. TFT screen is adopted to display the processed video results at real time. Auto-read tracking algorithm is a combined method of image interframe difference and background difference. Thus the moving target is detected in the static background. Then according to the position of the moving measuring mark calculate the angular displacement.

Abstract. With the development of space optical remote sensing imaging technology, Space remote sensing systems have reached a new stage which is changing towards higher spatial resolution, higher spectral resolution, higher radiometric resolution, and higher temporal resolution. In recent years, applying TDI CCD to earth observation from space has become a growing trend, and it can make integrals to the same moving target by using multilevel sensitive units, which has improved the S/N and the dynamic range of optical system effectively. This paper proposes a semi-physical simulation system designed for space optical remote sensing based on 6-DOF motion platform. The system ignores the atmospheric radiation and it can obtain high quality images by simulating the whole physical process of the space optical remote sensing imaging chain which includes the sensor of TDI CCD, the motion platform of satellite, the ground scene, and the access to final remote sensing.
