【期刊论文】Incoherent pulse Doppler lidar as the velocimeter system

This note reports a new type of incoherent pulse laser Doppler lidar velocimeter with iodine molecular filter as a frequency discriminator. Its transmitter subsystem applies a Nd: YAG pulse laser which is injected with a single longitudinal-mode diode pumped continuous seeder laser. The field experiment proved that this velocimeter measurement results are consistent with those measured by photoelectric velocimeter. Measurements of eight different velocities show that the standard deviation is 0.56m/s, the range resolution is 3.75m.

【期刊论文】MULTICHANNEL FOURIER TRANSFORM OPTICAL FEEDBACK IMAGE PROCESSING
刘智深, LIU ZHISHEN AND HE MINGXIA
KEXUE TONGBAO 1984 Vol. 29 No.8 1013~1016,-0001,():

A multichannel optical Fourier transform has been proved to be a useful method for encoding spatial-frequency or density pseudoeolor[1]. The method of image-processing is accomplished by spatial-filtering the various time frequency channels. Compared with the Ronehi grating methods[2], this method has the advantages of high utilization ratio of light source, has no image resolution loss caused by grating sampling and does not require Fourier transforming lenses of large relative aperture.
