If the objective lens is further away from the compact disk than the focal length of the object lens, then the cylindrical lens again creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離長於物鏡的焦距,柱面透鏡也會使在光電探測器陣列上的成像變成橢圓影像。The project adopts pulsed laser ranging in noncoherent detect mode, uses a 905nm pulsed laser diode as the laser source, detects object with a single apd, adopts an optics - mechanics scanner in object space to obtain images, and obtain distance images and intensity images of object simultaneously
該研究方案採用直接探測脈沖激光測距體制,以波長為905nm的脈沖半導體激光器作為激光光源,利用單元apd探測器進行探測,採用物空間掃描的光機掃描方式進行掃描成像,能同時獲得目標的距離圖像和強度圖像。Secondly, the wavelength of light source and the distance between the source and detector, two key parameters in reflectance sensor design, are determined according to theory in light transmitting and experiments in lab. thus the sensitivity and dependability in reflectance monitoring is improved as much as possible
本文接下來討論了反射式血氧探頭中兩個重要參數? ?光源波長的選擇和光源與接收器之間距離的確定,以保證在反射檢測中能獲得最高的血氧測量靈敏度和可靠性。The simulated results show that we can improve the sensitivity by setting the optical bias at / 2, reducing the gap of electrode, increasing the overlap integral factor, reducing the insert lose, adopting suitable segmentation number, increasing the electrode length, increasing the optical power, reducing the wavelength and the relative intensity noise and reducing the receive bandwidth ; obtain the wider bandwidth utilizing reducing the electrode length and the capacitance of modulator, segmentation the electrode ; increase the dynamic range using lowering noise, increasing the optical power at the detector and lower optical bias
通過計算得知,使傳感器相位偏置為/ 2 ,減小電極間距,提高電光重疊因子,減小器件插入損耗,採用合適的分段數,增加電極長度,增大光功率,降低激光的波長,減小相對強度噪聲,減小接收帶寬,對提高靈敏度的效果是非常明顯的。而減小天線長度,降低調制器電容,電極分段,都可以獲取較大的帶寬。降低系統噪聲;增加到達探測器的光功率,採用較低的光學偏置,都可以增大線性動態范圍。21a / w, and a1so get some other significative resul t. mair1 works and resu1t inc1ude : ( l ) by ana1yzing the the working pril1ci p1es of gan - - based msm ph ( ) to - detectors, we designed the two ki11ds of di fferent structure parameter of device. the electrode fingers are 2 p m wide, and l00 ll nl long, the gap.
本文的主要工作和結果有: ( 1 )通過對gan的msm結構探測器的工作原理的分析,我們設計了兩種尺寸的器件結構參數,確定了器件的金屬電極條寬為2 m ,長為100 m ,電極間距分別為6 m 、 10 m兩種,器件有效面積分別為104 m 155 m 、 150 m 155 m 。分享友人
