Abstract
A BSO spatial light modulator (BSO-SLM) was operated applying ac voltage. The basic properties of the operation correspond to those in a usual lock-in detector and a 2-dimensional lock-in detector array (2D-LOCKIN) was implemented by the optical modulator. The properties of the 2D-LOCK-IN using a BSO-SLM were investigated theoretically and experimentally. As an application of the 2D-LOCK-IN, oscillating amplitude were observed on simple vibrating objects.
