    Abstract: A sensor head for monitoring radiated laser energy is disclosed which uties a transparent scatter plate placed in the path of the laser beam. A plurality of regularly spaced photodetector diodes are secured to its outer edge. The scatter plate and photodiode configuration are contained in a mounting bracket and frame assembly which permits its attachment to a front of a variety of laser systems without requiring modification of those systems. As radiation from the incident laser beam is transmitted through the plate, a small portion of the laser energy is coupled to the diodes via microscopic scattering sites in the plate. The signal output from the four diodes is combined by signal summing to provide a measure of the energy at peak power output of the laser without distorting or perturbing transmitted beam.

    Abstract: An optical sensor module and a packaging method thereof are disclosed, wherein the optical sensor module comprises a substrate having a light sensing element; and a housing made of a transparent material. The housing is connected to the substrate and covers the light sensing element. The housing has a light-receiving area facing the light sensing element, and the inner surface of the housing toward the substrate is provided with a light-shielding coating in a portion outside of the light-receiving area. In this way, optical components such as the light sensor can be effectively protected, and still retain the effect of avoiding noise light interference with the light sensor module.
