本文主要探讨了在非均匀介质中简化格雷戈里·恩斯透镜（GRIN）等效单镜头系统的设计与应用。GRIN透镜是一种特殊类型的光学元件，其折射率沿径向轴线逐渐变化，从而实现对光线的有效弯曲和成像，类似于传统的玻璃透镜。然而，与球面透镜不同，GRIN透镜的特点是具有平坦的端面，这使得它们在设计复杂光学系统时更具优势，特别是在非均匀介质环境中。 矩阵光学技术在此文中被用来构建这些简化等效系统，其核心思想是通过数学模型将复杂的GRIN透镜行为转化为易于理解和分析的一维或二维光学模型。这种方法简化了对GRIN透镜在非均匀介质中成像特性的分析，如焦距、分辨率和场曲等关键参数的计算。这对于设计和优化集成光电子系统至关重要，因为这些系统经常需要处理光的传播路径和相位变化，而GRIN透镜因其特性能够有效地解决这些问题。 文章作者Xiang Shou强调，使用这种简单等效系统可以节省大量的设计时间和资源，便于工程师快速评估不同GRIN透镜配置在实际应用中的性能，例如在光纤通信、生物医学成像或者光束引导等场景。同时，由于GRIN透镜的自适应性质，它们在空间光波导、光纤通信和光学数据存储等领域具有广泛的应用潜力。 本文的研究成果发表于2010年7月，被标记为光学领域的关键代码：070.2590（非均匀介质光学）、080.2468（矩阵光学方法）、080.2730（一阶光学设计）和110.2760（光电子系统设计）。该研究为光学设计者提供了一种实用工具，以便在实际应用中更好地利用GRIN透镜的优势，提升系统的性能和效率。

5. Add the count of equivalent pairs for each group to the variable initialized in step 3. 6. Return the final count of equivalent pairs. Here is an example implementation in Python: ```python def ...

Write a function that asks for a temperature in °F degrees Fahrenheit Compute the equivalent temperature in degrees
Celsius Show the converted temperature in degrees Celsius The function should keep running until no number is provided to convert You may want to use these functions:

f = input('Please enter temperature in degrees Fahrenheit (or press enter to quit): '); if isempty(f) break; end c = (f - 32) * 5/9; fprintf('%.2f degrees Fahrenheit is equivalent to %.2f ...

Write a python function called strToAscii with a parameter called message that returns the ASCII code equivalent of each character in the string represented by message and in the same order of appearance. For example, a partial ASCII table is provided below. Character ASCII 'a' 97 'b' 98 'c' 99 'd' 100 A call to strToAscii('abdc') will result in, >>>print(strToAscii('abdc')) 979810099 >>>print(strToAscii('ccad')) 999997100 Requirements and hints: (1) use local variable ascii_str for the desired computational result (resulted string) (2) argument should message, which is a string (3) use loop (4) use function ord(ch), which return the ASCII value of a character, e.g, ord('a') will be 97

We then use a `for` loop to iterate over each character `ch` in the input `message` string. For each character, we use the `ord` function to obtain its ASCII code value, which we then convert to a ...

Write a recursive function that prints the binary equivalent of an integer in C program

2023-05-22 上传
In this code, the `toBinary()` function is called recursively to print the binary equivalent of the input decimal number. The function takes an integer `num` as input and recursively divides it by 2 ...

for i in xrange(len(nums)):

2023-07-27 上传
It seems like you are trying to iterate over a sequence of numbers using a `for` loop in Python. However, the use of `xrange` suggests that you might be using Python 2.x instead of Python 3.x. In ...
