    • A peach sorting system (110) conveys peaches (114) on a conveyor belt (112) past an inspection zone (126) that is lighted by an illumination source (90) radiating a number of emission peaks over visible and infrared portions of the spectrum. The illumination source generates the radiation from an Indium Iodide lamp (92) that is reflected off a parabolic reflector (94) and through a “soda straw” collimator (100) to illuminated the peaches. A detector system (118) employs line scanning visible and infrared cameras (142, 140) to sense visible and IR wavelength reflectance value differences existing between peach meat (124) and peach pit or pit fragments (126). Because there is a reversal in the reflectance values between the visible and infrared wavelengths, a data subtraction technique (150) is employed to enhance the detection contrast ratio. The data subtraction technique also cancels “glint” caused by specular reflections of the illumination source off the peaches and into the cameras.
    • 桃分选系统(110)将传送带(112)上的桃(114)传送通过照射源(90)照射的检查区(126),所述照明源(90)在光谱的可见光和红外部分上辐射多个发射峰 。 照明源产生来自抛物面反射器(94)并通过“苏打吸管”准直器(100)反射的碘化铟灯(92)的照射以照亮桃子。 检测器系统(118)使用线扫描可见光和红外相机(142,140)来感测存在于桃肉(124)和桃子坑或坑碎片(126)之间的可见光和IR波长反射率值差。 因为可见光和红外波长之间的反射率值有反转,所以采用数据减法技术(150)来提高检测对比度。 数据减法技术还可以消除由于桃子和相机中的照明源的镜面反射引起的“闪烁”。
