Application Note

Laser Speckle Reduction Solution in Projector Based on MSPM0 MCU

Abstract

As a general-purpose MCU product, MSPM0 has the feature of complete peripherals and high cost performance, making the Laser Speckle Reduction more flexible and low-cost. This application note is a guide for the implementation of Laser Speckle Reduction based on MSPM0, including several methods to generate the required PWM waveform and test result. In addition, this document provides a method to calibrate the event and interrupt delay between peripherals.

1 Introduction

In projectors, there are several light source technologies. Among them, triple color laser is a projector light source technology with high brightness, wide color gamut and long life. Lasers have inherently high coherence. When lasers are irradiated onto optically rough surfaces, the coherent light interferes and produces a granular speckle pattern with light and dark transitions. Laser speckle affects the image contrast and resolution. Therefore, in three color projector application, laser speckle reduction technology is needed.
