InGaAs linear image sensor
The G10768-1024D is a 1024-channel, high-speed infrared image sensor designed for applications such as foreign object screening and medical diagnostic equipment where a multichannel high-speed line rate is required. The signal processing circuit uses CTIA (Capacitive Transimpedance amplifiers) that allow signal readout while simultaneously integrating signals in all pixels via sample-and-hold circuits. A high-speed line rate is achieved through 8 output ports.
Light from a broadband wavelength light source is shone on the sample, the interference light spectrally dispersed, then detected by a linear image sensor. An image in the depth direction of the sample is acquired by Fourier transforming the obtained wavelength information.
This linear image sensor with rectangular pixels, high line rate, and a global shutter function is appropriate for absolute track reading of linear encoders.
