This International Standard is applicable to optical imaging systems in the optical spectral region from λ = 100 nm to λ = 1 μm. Theoretical reflections and the comparison with the calculation apply only to optical systems. These need not, however, be rotationally symmetric; anamorphic systems, for example, are included. Telescopic systems are also included. The title of this International Standard refers to the relative irradiance in the image field, but this standard is also applicable to determination of the relative radiant power. NOTE — For telescopic systems it will be suitable to state only the radiant power; for most imaging systems, the conversion from radiant power to irradiance will be easy. As far as measurements are concerned, this International Standard can also be applied to electro-optical systems. The two methods described differ particularly in the influence of veiling glare.
对于镜头设计及生产厂家,一般用光学传递函数OTF(Optical Transfer Function)来综合评价镜头成像质量,光学系统传递的是亮度沿空间分布的信息,光学系统在传递被摄景物信息时,被传递之各空间频率的正弦波信号,其调制度和位相在成实际像时的变化,均为空间频率的函数,此函数称为光学传递函数。...
物面与像面亮度关系为: (1)式中:τ为光学系统的透射比;n’和n为像方和物方的折射率,通常n’≈ n ≈ 1。则上式简化为L’=τL。可以通过测量成像面上的亮度来测量发光体的亮度。...
内窥镜光学测试系统用于医用内窥镜摄像系统的测验方法及所需测试设备,适用于内窥镜检查和手术中作为内窥镜功能供给装置的医用内窥镜摄像系统。 通过本测试方案可用于测量摄像系统的亮度响应特性,摄像系统的信噪比,摄像系统的空间频率响应以及摄像系统的静态图像宽容度。...
这种热像图与物体表面的热分布场相对应; 实质上是被测目标物体各部分红外辐射的热像分布图由于信号非常弱,与可见光图像相比,缺少层次和立体感; 因此,在实际动作过程中为更有效地判断被测目标的红外热分布场,常采用一些辅助措施来增加仪器的实用功能; 如图像亮度、对比度的控制,实标校正,伪色彩描绘等高线和直方进行数学运算、打印等。 标签: 红外热像仪...
