一、红外线领域的光弹性测定1.序言光弹性的一般法则,适用于非常广泛的连续频率范围,并且已达到了超越可见领域的长波长(红外线)领域。在可见领域外进行光弹性测定时,成问题的只是能否使用光源、偏振光镜、四分之一波长板、光学元件和检测器等。伴随光电子技术和红外技术的迅速发展,目前已经开始在比较长波长的领域进行测定了。选择用于某种特殊用途的波长时,就系统
I. Photoelastic Determination in the Infrared Field 1. Introduction The general law of photoelasticity applies to a very wide range of continuous frequencies and has reached the field of long wavelengths (infrared) beyond the visible field. When performing photoelasticity measurements outside of the visible area, the only problem is the availability of light sources, polarizers, quarter-wave plates, optical components and detectors. With the rapid development of optoelectronic technology and infrared technology, the measurement has been started in the field of longer wavelengths. When choosing a wavelength for a particular use, the system
