Patent ID: 7663740

Claim:
An optical power measuring apparatus capable of monitoring status of an optical fiber contact end face, comprising: a microscope camera module, configured to receive a visible light signal of an image of the optical fiber contact end face and transform the visible light signal into a digital image signal; an optical power detection unit, configured to receive an optical power signal passing through the optical fiber and transform the optical power signal into a specific electric signal; a display unit; a central processing unit, configured to control the transformation of the digital image signal and the specific electric signal into a first display signal and a second display signal respectively and output the first display signal or the second display signal to the display unit such that a user can monitor the cleanness status of the optical fiber contact end face or a value of the optical power signal on the display unit; an illuminating module, configured to emit a visible illuminating light to facilitate forming the image of the optical fiber contact end face; and an optical element, configured to reflect the visible light signal to the microscope camera module and having an optical reflection rate that changes in response to intensity of the visible illuminating light.
