Pentingnya MTF (Fungsi Transfer Modulasi) dalam Pengujian Tampilan AR\/VR\/MR<\/h2>\n

Ada banyak faktor utama yang perlu dipertimbangkan saat mengevaluasi tampilan AR\/VR\/MR, seperti bidang pandang (FOV) dan masalah seperti ghosting, distorsi, dll. Salah satu faktor penting yang perlu dipertimbangkan saat menguji tampilan AR\/VR\/MR adalah modulasi fungsi transfer (MTF). MTF adalah ukuran kuantitatif yang digunakan untuk mengevaluasi kualitas gambar optik, seperti lensa, optik AR\/VR, dll., dalam hal resolusi dan kontras.<\/p>\n

MTF sebagai Ukuran Kemampuan Sistem Metrologi Tampilan<\/strong><\/p>\n

Dalam konteks sistem metrologi tampilan, MTF menjelaskan kemampuan lensa sistem untuk mentransfer kontras dari suatu objek ke gambar pada resolusi tertentu. MTF adalah salah satu ukuran yang biasa digunakan untuk mengevaluasi kinerja resolusi dan kontras dari sistem metrologi tampilan. MTF yang rendah atau buruk dapat menimbulkan tantangan dalam menentukan apakah kinerja yang diamati merupakan hasil dari karakteristik bawaan perangkat yang diuji (DUT) atau keterbatasan lensa dan sistem secara keseluruhan.<\/p>\n

MTF sebagai Ukuran AR\/VR\/MR Menampilkan Kualitas Output Visual<\/strong><\/p>\n

Ketajaman atau kejelasan gambar yang diproyeksikan bergantung pada kemampuan tampilan AR\/VR\/MR untuk mewakili kontras secara akurat, yang memainkan peran penting dalam membedakan elemen gambar yang berbeda dan meningkatkan kualitas gambar secara keseluruhan. Kontras spasial tampilan AR\/VR\/MR terutama dievaluasi menggunakan MTF, yang memerlukan evaluasi perpotongan area gambar gelap dan terang menggunakan metode seperti Line Pairs (perhitungan kontras Michelson), Slant Edge, atau Line Spread.<\/p>\n

Pengukuran kontras spasial melalui MTF menggunakan metode Line Pairs melibatkan menampilkan garis sejajar dengan frekuensi spasial yang bervariasi dan mengukur kontras antara garis terang dan gelap. Orientasi pasangan garis bisa horizontal, vertikal, dll., dan kontrasnya dihitung menggunakan rumus kontras Michelson, yang membandingkan perbedaan intensitas antara garis terang dan gelap.<\/p>\n

Metode tepi miring melibatkan analisis profil tepi dari target tepi miring. Targetnya terdiri dari transisi mulus dari kawasan terang ke kawasan gelap, biasanya dalam bentuk garis miring atau irisan. Metode ini memanfaatkan fungsi penyebaran tepi untuk menggambarkan bagaimana cahaya menyebar melintasi transisi dari terang ke gelap. Setelah transformasi Fourier, kurva MTF diturunkan, yang mewakili kemampuan layar untuk mentransfer kontras pada frekuensi spasial yang berbeda.<\/p>\n

Metode Line Spread menggunakan satu baris piksel untuk mengukur Line Spread Function (LSF) secara langsung, bukan mengukur kontras tepinya. Metode ini ideal untuk mengevaluasi tampilan piksel. Hal ini bergantung pada perubahan frekuensi pada satu baris piksel yang menyala, sehingga menghilangkan masalah frekuensi piksel-ke-piksel yang muncul selama evaluasi tampilan piksel.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][vc_column_inner width=”4\/6″][vc_single_image image=”13116″ img_size=”full” alignment=”center”][vc_column_text css=””]<\/p>\n
