要调用Zemax并输出光学系统的场曲和畸变参数，你可以使用Python的subprocess模块来执行Zemax的命令行接口，并使用pywin32模块来读取Zemax生成的TXT文件。以下是一个示例程序，展示如何调用Zemax并输出场曲和畸变参数：
- import subprocess
- import win32com.client as win32
- def run_zemax_script(script):
- zemax_path = r"C:\Program Files\Zemax OpticStudio\Zemax64.exe" # 替换成你的Zemax安装路径
- cmd = [zemax_path, "-b", "-z", "c:\Temp\ZemaxScripts\temp.zpl"] # 将脚本保存到临时文件中
- try:
- with open(r"c:\Temp\ZemaxScripts\temp.zpl", "w") as f:
- f.write(script)
-
- result = subprocess.run(cmd, capture_output=True, text=True, timeout=30)
- return result.stdout
- except subprocess.TimeoutExpired:
- print("Zemax script execution timed out.")
- return None
- def read_zemax_txt(filename):
- excel = win32.Dispatch("Excel.Application")
- excel.Visible = False
-
- wb = excel.Workbooks.Open(filename)
- ws = wb.Worksheets(1)
-
- data = []
- for row in range(1, ws.UsedRange.Rows.Count + 1):
- data_row = []
- for col in range(1, ws.UsedRange.Columns.Count + 1):
- data_row.append(ws.Cells(row, col).Value)
- data.append(data_row)
-
- wb.Close()
- excel.Quit()
-
- return data
- # 定义Zemax脚本
- zemax_script = """
- NewFile,Sample.zmx
- AddSurface,10,10
- Tilt,1,1,1
- Run
- MCEX,11
- Paraxial,1
- """
- # 运行Zemax脚本
- output = run_zemax_script(zemax_script)
- if output is not None:
- # 解析输出，获取txt文件名
- txt_filename = ""
- lines = output.splitlines()
- for line in lines:
- if "Ray Database File: " in line:
- txt_filename = line.split(": ")[1]
- break
-
- if txt_filename:
- # 读取txt文件
- data = read_zemax_txt(txt_filename)
-
- # 输出场曲和畸变参数
- print("场曲：")
- for row in data:
- print(row)
-
- print("\n畸变参数：")
- distortion_params = data[-2][5:] # 假设畸变参数在倒数第二行，并且从第五列开始
- print(distortion_params)
- else:
- print("Failed to find Zemax txt file.")
- else:
- print("Failed to execute Zemax script.")
以上示例程序假设Zemax安装在Windows操作系统上的默认路径，你需要根据自己的实际情况修改`zemax_path`变量。程序会执行Zemax脚本，并从输出中提取生成的TXT文件的文件名。然后，使用pywin32模块中的Excel对象读取TXT文件中的数据，并将场曲和畸变参数分别输出到控制台。请注意，示例程序中的代码仅供参考，你可能需要根据实际情况进行适当的修改。
