随着电子计算机的发展和广泛应用,影像技术完成了从图像模拟到图像数字化的飞跃,从传统的光学系统(镜头)成像发展到计算机绘图和计算机动画。计算机绘图是利用电子束扫描将图像形成在荧光屏上。随着激光和激光技术的发展,与电子计算机相结合,形成一种新型的影像技术——激光演示技术,利用高亮度的激光束,通过激光扫描在屏幕或银幕上形成所要求的图像。 With the development and widespread application of electronic computers, imaging technology has taken a leap from image simulation to image digitization. From traditional optical system (lens) imaging to computer graphics and computer animation. Computer graphics is the use of electron beam scanning the image formed on the screen. With the development of laser and laser technology, combined with the computer, the formation of a new imaging technology - laser demonstration technology, the use of high-brightness laser beam, the laser scanning of the screen or screen to form the desired image.
