Near-infrared spectroscopy (NIRS) is an emerging non-invasive imaging modality. Along with its simplicity and flexibility, it can be portable which can be an advantage use to its applications used such as brain computer interfacing (BCI). Diffuse speckle contrast analysis (DSCA), which is developed based on diffuse correlation spectroscopy (DCS), measurements of blood flow variation in various tissues have been successfully validated against other superior imaging modalities like MRI and CT. It has showed that NIRS advantages such as noninvasiveness, high temporal resolution and relatively large penetration depth which can be comparable to other imaging modalities. In this report, the prototyping of single-channel brain blood flow monitoring device and the preliminary testing of the hemodynamic of the motor cortex has been reviewed using DSCA. It has shown promising results of the hemodynamic of the brain through the reflection of blood flow index that can be useful for other applications such as BCI.
