Abstract

The invention discloses a portable wide-spectrum multiple-target light source device which comprises an LED light source, an optical-axis indicating LD light source, an infrared radiation non-point source blackbody, a motor-driven multiple-target target wheel and a drive and control circuit. The device adopts a high-brightness LED light source system to replace an integrating sphere, so that the brightness is adjustable, and the detection requirements of indexes such as the white light resolution ratio is met. The device adopts a high-radiance differential infrared radiation source so as to meet the detection demand of infrared equipment. The device adopts a red-light LD to indicate an optical axis in real time, so that the docking of an optical system is convenient. The device adopts a motor-driven rotary target disk and a multiple-target structure so as to meet the multiple-index detection requirement of the system. The device adopts a precise motor-driven reflector assembly, so that the device can adjust an angle at random for optical path switching and optical axis steering and realize the matching and docking with different collimators. The device integrates a visible light / infrared radiation light source, a laser indicating light source and a multiple-target control, has the advantages of being advanced in technology, high in integration level, strong in controllability and portable, and is suitable for the field of index testing of optoelectronic equipment.
