Advanced Shutter + CMOS Structure for Real-Time Metering and Modular Exposure Control

[yao-1hhh]

I would like to propose an Advanced Shutter + CMOS System for integration into the existing LexOptical framework. (Sorry, I am a high school student that I may not contribute to this project by adding code)This design combines a mechanical shutter (front and back curtains) with a thin CMOS sensor(on front curtains), enabling real-time metering and preview functionality without disrupting traditional exposure workflows. The system is modular, ensuring compatibility with LexOptical’s open hardware philosophy.

(Since I am very not good at English writting, the translation is done by Chat GPT for better reading experience)

Motivation:

This feature is designed to enhance the flexibility of the LexOptical framework by:

Adding real-time metering and digital preview capabilities for film or hybrid systems.
Retaining the purity of optical exposure for traditional workflows, as the CMOS sensor moves out of the optical path during exposure.
Aligning with LexOptical's modular design philosophy, enabling easy upgrades and future integration.

Key Features:

1. Real-Time Metering:

The CMOS unit enables precise light measurement before exposure, ensuring high accuracy for various workflows.

2. Preview Functionality:
   Allows users to compose and evaluate their scene in real time.

3. Shutter Synchronization:
   Front curtain and CMOS move out of the optical path during exposure, with precise timing to ensure uninterrupted light delivery to film or the main sensor.

Modular Design:

The CMOS unit is compact (<1mm thick) and upgradeable, allowing easy replacement or enhancement as needed.

Challenges:

Precision Synchronization:
Ensuring the CMOS, front curtain, and back curtain movements are perfectly aligned.

Mechanical Wear:

Sliding mechanisms must be optimized to minimize wear over repeated usage.

Compact Integration:

Balancing CMOS functionality with space constraints, ensuring minimal impact on the system's overall size and weight.

Request for Feedback:

Is this idea feasible within the LexOptical framework?
Are there potential design challenges or conflicts with existing modules?
Are there any suggestions for preferred CMOS sensors or alternative design approaches?

Additional Notes:

I am a high school student passionate about hardware design and open-source projects. While I may not yet be able to contribute code or modeling, I would be thrilled to assist in drafting ideas, and working collaboratively with the community to refine this proposal. I look forward to your feedback and guidance!
