本研究設計與製造非球面陣列透鏡(Aspheric Lens Array, ALA)作為成像與照明兩種用途之光學元件。在本研究中，將探討成像用非球面陣列透鏡(Aspheric Lens Array for Image, ALA_M)之透鏡的成形複製與成像品質。透鏡性質包含鏡片高度(Sag)、非球面形狀誤差(Rt)、翹曲(Warpage)、有效焦長(Effective Focal Length, EFL)、波前誤差(Wavefront errors)、調制轉換函數(Modulation Transfer Function, MTF)和光斑直徑(Spot Diameter, Ds)，最後再藉由ALA_M於可調控焦距機制之成像品質測試，藉此探討模具溫度對於成形與光學品質之影響性。實驗結果發現，當模具溫度為90oC時，非球面形狀誤差之最小平均值為1.088 μm。應用可調控焦距機構於ALA_M時，可得到最小調控距離平均值為2.58 mm。ALA_M的非球面形狀誤差、有效焦長、波前誤差、光斑直徑與模具溫度有關。在照明用非球面陣列透鏡(Aspheric Lens Array for Illumination, ALA_L)之照明性質(Illuminance)方面，藉由所設計之ALA_L改善LED之中心照度值。從ALA_L(照明)之中心照度實驗結果中，得知ALA_L(照明)之中心照度值由51.4勒克斯(lux)提升到56.2勒克斯(lux)，有效提高8.53%。本研究成果可應用於下世代之多透視相機鏡頭與多鏡頭陣列。

This research is to design and fabricate two type of Aspheric Lens Array (ALA) for image (M) and illumination (L). In this research, the Aspheric Lens Array for Image (ALA_M) has been studied to investigate the relationship between molding replicate of lens and optical image properties. Typical lens properties including Sag, form error (Rt), warpage, effective focal length (EFL), wavefront errors, modulation transfer function (MTF) and spot diameter (Ds) have been measured and discussed. An adjust-focal-length mechanism has been developed to test optical image properties. For ALA_M, the Rt can be achieved as 1.088μm when the mold temperature is set at 90oC during injection molding. The minimum average delta length (△L) as low as 2.58mm can be achieved when the ALA_M is used with adjust-focal-length mechanism. From experimental results, the mold temperature significantly affects on the aspheric form error, effective focal length, wavefront error and spot diameter of ALA_M. For the Aspheric Lens Array for Illumination (ALA_L), the center illuminance has been measured by light meter. From experiment results, the center illumination of the ALA_L can be improved from the original 51.4 lux to 56.2 lux. This research results can be used for the next generation multi-perspective camera and multi-camera lens array.
