(291) The paper mainly introduces the design project of HFC forward transmission network in Antu County, including scheme, technique index and system index testing of optical cable transmission network.

(292) G-APD array detector has two outstanding characters: single photon sensitivity and pico-second resolving power, which makes the detector very suitable for the weak optical signal 3-D imaging.

(293) Two special optical devices LCLC - lens are introduced, and their design philosophy and structures are descibed.

(294) OCR ( Optical Character Recognition ) is an important branch of pattern recognition.
