Aichi Sangyo, which has continually acted as an "interface" for the industrial world as an importer of various new technologies from around the world since its establishment, exhibited a high-end microscope that can measure three-dimensional nano structures in real time at the 2008 Finetech Expo. The digital holographic microscope uses a hologram to display high-resolution, 3D images of samples in real-time. The holograph is produced from the interference between a reference light and coherent light emitted from the sample. The hologram is sent via a video camera to a PC for storage and is separated into phase and amplitude signals, when these two signals are restructured, 3D images can be displayed in real time. Then entire wavefront that is bounced back from the object to be captured is calculated from one hologram that is recorded at a high speed of several micro seconds. From this, images equivalent to those from optical microscopes can be obtained from the strength of the amplitude. In addition, the phase information contains measurement information at a resolution that is the same scale as the wavelength, and this information can be used to make proper measurements. In the future, Aichi Sangyo intends to expand its product development and research into various other fields such as display technology.
