研究目的
Investigating the influence of the brightness amplifier operation mode on images formed with a bistatic laser monitor and evaluating the possibility of imaging remote objects with this instrument.
研究成果
The study demonstrates the capabilities and limitations of a bistatic laser monitor, showing that imaging distances can attain 15.5 m with optimization. The concentration of the active substance significantly affects the gain factor and image quality, with an optimal temperature of 550°C identified for effective amplification. Artifacts such as light-exposed regions and flares can be minimized by careful selection of the active substance temperature and exposure time.
研究不足
The study is limited by the operational characteristics of the active element pumping sources and measuring equipment, including a jitter of no less than 7 ns in light pulse recording. The resolution threshold of the optical system is also a limiting factor at certain imaging distances.
1：Experimental Design and Method Selection:
The study involves a bistatic laser monitor prototype with two CuBr vapor active elements. The work is coordinated with a synchronizing system.
2：Sample Selection and Data Sources:
A monochromator slit with an opening of
3：44 mm is used as the test object. List of Experimental Equipment and Materials:
Includes illumination source, brightness amplifier, neutral filters, lenses (OKP1-350-1 and Hellios 44-2), power meter (Ophir 30C-SH), light pulse recorders (FEK-22SPU-M), oscilloscope (LeCroy WJ324 A), and Baumer VLG-20C camera.
4：Experimental Procedures and Operational Workflow:
The distance between the test object and brightness amplifier varies from 5 to
5：5 m. The temperature of the active substance is varied to study its effect on the gain factor. Data Analysis Methods:
The gain factor is defined as the ratio of the radiation power at the amplifier output to the power of an input signal. The influence of the active substance temperature on the gain factor and image quality is analyzed.
