Brief introduction:
With the rapid development of the optical communication industry, especially the continuous improvement of the imaging quality requirements of mobile phones and tablets in the communication industry, it is necessary to detect and analyze the transmission wavefront of optical glass in the camera hole of mobile phone panel. The transmission wavefront of optical glass refers to the interference between the light reflected from the standard reference mirror and the light reflected from the standard reflector.
The interference fringe reflects the quality of the transmission wavefront of the camera hole on the mobile phone panel. Specific methods for the interferometer with standard reference mirror injection parallel light, standard reflector in d slide table, by adjusting knob interference fringes can be divided into two-dimensional zero stripes, now and then camera phone panel holes on their interference in the cavity, the monitor will appear camera hole transmission wavefront interference fringes, through quality and quantity of the interference streak on a distant can judge camera phone panel hole processing after the degree of influence on image quality of imaging system. In simple terms, the interferometer is used to detect whether the camera hole on the mobile phone panel is flat and the image of the mobile phone is OK. Technical parameters:
