Based on the formula of information capacity for an optical system,the scanning resolution and signal-to-noise ratio for biochip confocal scanning system were studied under both different laser focused spot sizes and different detector pinhole sizes respectively.

Confocal scanning optical microscopy (CSOM) includes transmission type and reflection type as well as coherent incident light type and incoherent fluorescent light type.

We report a new method of photoacoustic imaging with depth profiling, based on photoacoustic Fourier transform confocal scanning imaging, which can produce images of scattering medium such as tissue.

The improvements include evaluating the scan point through two steps, and considering more special conditions in calculating the high side datum scan angle through north-datum scan angle.

Research of excimer laser corneal surgery and flying-spot scanning algorithm;

The small scanning-spot excimer laser corneal system was developed based on flying-spot scanning model.

The paper revie ws the flying-spot scanning Excimer laser corneal surgery system with own proper ty right at home in terms of the principle of correction, exclusive high quality optical system and so on, and obtains very successful effect in clinical animal s and blind eyes experiment.
