Abstract: The present invention discloses a time-sequential multi-spectrum image acquiring device structure which uses a single camera module to achieve multi-spectrum image acquiring in a time-sequential architecture, thereby providing a simple, lightweight telemetry system and reducing the development and operation costs thereof. For example, a visible and near infrared (VNIR) imaging system reduces the use of four camera modules (each including an optical lens, filter, sensor, and image signal processing unit) to single camera module, the VNIR imaging system acquires multi-spectrum images having the same image geometric parameters for image calibration and can simplify the calibration process.The present invention is implemented by introducing a multi-spectrum filter wheel capable of rotating in high speed in the camera module and controlling the image acquiring frequency of the sensor and the synchronicity of the wheel rotating speed for multi-spectrum image acquiring. The present invention is suitable for use in multi-spectrum images acquiring of airborne telemetry requiring lightweight system, such as multi-spectrum images acquiring of unmanned aerial vehicle (UAV).

Abstract: Voltage generating apparatus includes a positive temperature coefficient current generating module, a negative temperature coefficient current generating module, a fine-tune current module and a voltage output module. The function of the positive temperature coefficient current generating module and the negative temperature coefficient current generating module, which take advantage of characteristics of MOS devices operated in the sub-threshold region, is to generate a stable current of positive temperature coefficient and a stable current of negative temperature coefficient, respectively. The current fine-tune module increases or decreases output current of the negative temperature coefficient current generating module. The voltage output module sums two output currents of the positive temperature coefficient current generating module and the negative temperature coefficient current generating module and transforms the total current into output voltage that is stable under temperature and process variation.
