This Fourier lens system is often used in optical signal processing system. Based on the design principles of Fourier lens system and the requirements of some particles observation experiment
a Fourier optical system whose working wavelength was 532nm was designed using ZEMAX. The testing experiment using the visual microscope
showed that the system's resolution was 250lp/mm. And the system was successfully used in the particles observation experiment. 2011 IEEE.

With the development of optical information processing
high-resolution Fourier transform lens has often been used in holographic data storage system
spatial filtering and observation of particles. This paper studies the optical design method of high-resolution Fourier transform optical lenses system
which could be used in particles observation and holographic data storage system. According to Fourier transform relation between object and its frequency plane and the theory of geometrical optics
the system with working wavelength 532nm and resolution 3 m was designed based on ZEMAX. A multi-configuration method was adopted to optimize the system's lenses. In the optical system
a diaphragm was placed at the system's spectrum plane and the system demanded a low vacuum to cut down the influences of atmosphere and other particles. The result of finite element analysis indicated that the influences of vacuum pumping to optics spacing and mirror surface shape very minor
and the imaging quality not being affected. This system has many advantages
such as simple structure
good image quality and a high resolution of 3 m. So it has a wide application prospect and can be used both in holographic data storage system and particles observation.

The work on laser varicose treatment carried out in CIOMP
It provides minimal invasion
CAS cooperating with The First Clinical Hospital
often under local anesthesia and intravenous sedation thereby eliminating the need for general anesthesia
Jilin University is summarized. Dozens of animal experiments adopting dog and rabbit samples are made in a long time of several years. Different lasers are used
greatly shortens postoperative recovery term
including long pulse frequency-doubled Nd:YAG(532nm) and semiconductor laser(808nm). Dozens of animal experiments show that laser has good efficacy to occlude the vein vessels. It has precise adjustability and relatively short treatment time only needing outpatient office setting with high cost and effect rate
and it is highly safe with no side effects and no serious complications.

Laser treatment represents an attractive option to other methods of vessel diseases especially varicose veins. A long pulse (30-50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3)
the vessels are usually irradiated to perforate
detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein's occlusion
which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.

This paper will introduce the principle and techniques to realize laser color video display. The characteristics of techniques and bottleneck of restricting the development are analyzed. A novel technical approach to eliminating the laser interference
improving the uniformity of optical field
transforming the chromaticity and extending the virtual color is proposed. The principle device of laser display system has been produced on the basis of the blue
green and red diode-pumped solid state lasers. The wavelengths of the blue
green and red are respectively 473nm
532nm and 671 nm. The output powers of the lasers are 1.3W
0.32W and 3.5W respectively.
